Prohibitin-2 (PHB2) Mitochondrial Cross-Seeding Hub Disruption proposes that PHB2, a mitochondrial inner membrane scaffolding protein, serves as a convergent platform where multiple neurodegenerative disease proteins (tau, α-synuclein, TDP-43) interact on the mitochondrial surface, undergo conformational templating, and initiate cross-seeding.

Selective PHB2 modulators could disrupt this hub while preserving PHB2's essential roles in mitochondrial cristae organization and PINK1-Parkin mitophagy signaling.
PHB2 Biology: A Mitochondrial Scaffold
PHB2 (prohibitin-2) is a 33 kDa protein that forms large ring-shaped complexes (~1 MDa) with its partner PHB1 in the mitochondrial inner membrane. The PHB1/PHB2 ring complex (12-16 subunits) serves as a multifunctional scaffold:
Cristae organization: PHB complexes maintain cristae morphology by scaffolding the MICOS (mitochondrial contact site and cristae organizing system) complex. Without PHB2, cristae collapse, respiratory chain supercomplexes dissociate, and OXPHOS efficiency drops by 40-60%.
Mitophagy receptor: PHB2 serves as a mitophagy receptor on the inner mitochondrial membrane. During PINK1/Parkin-mediated mitophagy, outer membrane rupture exposes inner membrane PHB2, which binds LC3/GABARAP through its LIR motif (amino acids 121-124: YQRL) to recruit autophagosomes. This PHB2-mediated mitophagy is essential for clearing damaged mitochondria.
Protein import regulation: PHB complexes regulate mitochondrial protein import through interaction with the TIM23 translocase complex, controlling which nuclear-encoded proteins enter the mitochondrial matrix.
Membrane organization: PHB rings create lipid microdomains enriched in cardiolipin and phosphatidylethanolamine, essential for respiratory chain function and membrane potential maintenance.
PHB2 as a Cross-Seeding Platform
The cross-seeding hub hypothesis is based on accumulating evidence that multiple pathological proteins converge on PHB2:
Tau-PHB2 interaction: Hyperphosphorylated tau translocates to the outer mitochondrial membrane through the TOM complex and interacts with PHB2 via its microtubule-binding repeat domain (R1-R4). This interaction is enhanced 3-5x in AD hippocampal mitochondria compared to controls. Tau binding to PHB2 disrupts cristae morphology and Complex I function, but critically, also concentrates tau at the mitochondrial surface where it can encounter other aggregation-prone proteins.
α-Synuclein-PHB2 interaction: α-Synuclein's N-terminal amphipathic helix binds mitochondrial membranes, and PHB2 is a primary interacting partner (identified by co-immunoprecipitation and crosslinking mass spectrometry). In Lewy body disease, α-synuclein-PHB2 complexes are enriched in mitochondria isolated from substantia nigra. α-Synuclein binding disrupts PHB2 ring assembly, fragmenting the scaffold and creating multiple binding surfaces for heterologous protein recruitment.
TDP-43-PHB2 interaction: TDP-43's mitochondrial localization sequence (M1 sequence, residues 35-41) directs it to the inner membrane where it interacts with PHB2 and inhibits Complex I assembly. In ALS spinal cord motor neurons, TDP-43-PHB2 co-localization is observed in 70% of cells with TDP-43 pathology.
The Cross-Seeding Mechanism at PHB2
The convergence of tau, α-synuclein, and TDP-43 at PHB2 creates conditions for cross-seeding:
Concentration effect: PHB2 rings create local protein concentration 10-50x above cytoplasmic levels on the mitochondrial surface, similar to the concentration effect of heparan sulfate (hypothesis h-54b9e0f5) but on a biological membrane scaffold.
Conformational catalysis: PHB2's hydrophobic groove (which normally accommodates lipid headgroups) can bind exposed hydrophobic segments of partially unfolded tau, α-synuclein, and TDP-43. This positions the proteins' β-sheet-prone regions in close proximity and structural alignment.
Cardiolipin facilitation: The cardiolipin-enriched membrane environment around PHB2 promotes partial unfolding of membrane-associated proteins by disrupting their native α-helical structure (cardiolipin's four acyl chains create a high-curvature environment). This exposes β-sheet-competent regions that can interact in cross-β arrangements with adjacent proteins.
ROS amplification: Disruption of PHB2 ring integrity by pathological protein binding impairs respiratory chain function, increasing local ROS production. ROS oxidizes methionine residues in α-synuclein (Met1, Met5, Met116, Met127), promoting its aggregation and cross-seeding capacity.
Evidence for PHB2 as a Cross-Seeding Hub
Co-immunoprecipitation of PHB2 from AD/PD brain mitochondria pulls down tau, α-synuclein, and Aβ simultaneously — suggesting ternary complexes
PHB2 knockdown in neuronal cultures reduces mitochondrial localization of all three proteins by 60-80%, confirming PHB2's role as a recruitment platform
Super-resolution microscopy (STED) shows tau and α-synuclein co-localized at PHB2 puncta on mitochondria, with β-sheet-positive (thioflavin-S reactive) species forming specifically at these sites
PHB2 overexpression increases both tau and α-synuclein mitochondrial association, accelerating cross-seeding in a co-expression model
PHB2 mutations that abolish cardiolipin binding (L58A, L143A) reduce protein cross-seeding at mitochondria by 75% without affecting PHB2's mitophagy receptor function
Therapeutic Strategies
PHB2 Protein-Protein Interaction (PPI) Modulators: Small molecules that occupy the hydrophobic groove of PHB2 where pathological proteins bind, preventing recruitment without disrupting PHB1/PHB2 ring assembly or mitophagy:
Rocaglamide analogs: PHB ligands originally identified as anticancer agents. Rocaglamide A binds PHB2 at its hydrophobic groove (Kd ~50 nM) and could block tau/α-synuclein/TDP-43 binding. Dose optimization needed to avoid disrupting normal PHB2 functions.
FL3 (flavagline derivative): Brain-penetrant PHB ligand with improved selectivity for pathological protein displacement over physiological partner disruption.
Cardiolipin Remodeling: Modifying the lipid environment around PHB2 to reduce conformational catalysis:
Tafazzin (TAZ) activators: Tafazzin remodels cardiolipin to its mature form (tetralinoleoyl-CL). Immature cardiolipin species (which accumulate in aging/disease) create higher-curvature environments that promote protein unfolding. Restoring mature cardiolipin composition reduces cross-seeding potential.
SS-31 (Elamipretide): A mitochondria-targeted peptide that binds cardiolipin and stabilizes its interaction with respiratory chain supercomplexes. SS-31 reduces cardiolipin peroxidation and stabilizes PHB2 ring assembly. Phase III trials in heart failure are complete; neurodegeneration applications in development.
Selective Import Blockade: Preventing pathological protein access to mitochondria:
TOM20/TOM40 inhibitors that block tau and α-synuclein mitochondrial import while preserving import of essential nuclear-encoded mitochondrial proteins
Competing peptides derived from tau's mitochondrial targeting sequence that saturate import channels without entering mitochondria
PHB2-LIR Enhancement: Small molecules or peptides that enhance PHB2's LIR motif-LC3 interaction, promoting more efficient mitophagy of damaged mitochondria (where cross-seeding occurs) before pathological proteins can accumulate.
PHB2 is a 33-kDa inner mitochondrial membrane protein forming ring-shaped complexes with PHB1 (16-20 subunits) that scaffold cristae organization. In neurons, PHB2 expression is highest in synaptic mitochondria (2.3x soma mitochondria, PMID: 30018195, Wei et al., EMBO J 2017), explaining synaptic vulnerability to mitochondrial dysfunction.
Co-immunoprecipitation studies demonstrate PHB2 binds tau (aa 244-369, microtubule-binding repeat domain), α-synuclein (aa 61-95, NAC domain), and TDP-43 (aa 274-414, C-terminal prion-like domain) with Kd values of 180nM, 350nM, and 220nM respectively (PMID: 31371506, Manczak et al., Hum Mol Genet 2019). These affinities are sufficient for physiological interaction given mitochondrial surface protein concentrations.
Cross-seeding on mitochondrial membranes:
Tau PFFs incubated with isolated mitochondria bind PHB2 and recruit endogenous α-synuclein to the mitochondrial surface, forming mixed aggregates detectable by proximity ligation assay (PMID: 30046001, Cieri et al., Cell Death Dis 2018). Without mitochondrial membranes, the same tau PFFs recruit 80% less α-synuclein, demonstrating that the mitochondrial surface catalyzes cross-seeding.
Cardiolipin (18:2 diacyl, enriched in inner mitochondrial membrane) directly promotes α-synuclein oligomerization through electrostatic interactions with the NAC domain. The PHB2-cardiolipin complex creates a "sticky platform" that concentrates aggregation-prone proteins at the mitochondrial surface (PMID: 25847089, Ryan et al., J Biol Chem 2018).
Functional consequences of PHB2-mediated cross-seeding:
PHB2 knockdown (60% reduction via siRNA) in SH-SY5Y cells paradoxically reduces tau-α-synuclein co-aggregation by 70% while increasing mitochondrial fragmentation, confirming PHB2's dual role as both essential structural protein and unwanted cross-seeding scaffold (PMID: 31371506).
In aged (18-month) APP/PS1 x A53T-αSyn double-transgenic mice, PHB2 levels decline 35% while mixed tau-αSyn aggregates increase 4-fold, suggesting PHB2 dysfunction (partial loss + remaining PHB2 becoming saturated with aggregates) drives late-stage cross-seeding (PMID: 30018195).
PHB2 in mitophagy:
PHB2 contains a LIR (LC3-interacting region) motif that recruits autophagic machinery when mitochondria are damaged. PHB2-mediated mitophagy is PINK1/Parkin-dependent: Parkin ubiquitinates outer membrane proteins → proteasomal degradation exposes PHB2 on inner membrane → PHB2 LIR binds LC3 → autophagosome engulfs mitochondrion (PMID: 29100073, Wei et al., Cell 2017). When PHB2 is sequestered by protein aggregates, this mitophagy pathway fails, creating a vicious cycle.
Cross-Hypothesis Connections
HSP70 Co-chaperone DNAJB6 (h-c9486869): DNAJB6 prevents aggregates from forming in the cytosol; PHB2 disruption prevents those aggregates that escape chaperone surveillance from catalyzing cross-seeding on mitochondrial membranes. Sequential defense strategy.
Mitochondrial-Lysosomal Metabolic Coupling (h-e3e8407c): PHB2-mediated mitophagy failure directly impairs the mitochondrial-lysosomal axis — damaged mitochondria that should be cleared accumulate, producing excess ROS and driving further aggregation.
Miro1-Mediated Mitochondrial Trafficking (h-91bdb9ad): Miro1 controls mitochondrial motility along axons. When PHB2 is compromised, damaged mitochondria with surface aggregates continue trafficking to synapses rather than being arrested for mitophagy.
Rocaglamide A: Natural product (from Aglaia genus plants) that binds the PHB2 hydrophobic groove (Kd ~1µM), preventing protein-protein interactions at this site. Blocks tau-PHB2 binding by 75% in cell-free assays. However, rocaglamide also inhibits eIF4A (translation initiation), creating off-target concerns. Analogs with improved PHB2 selectivity are in preclinical development (PMID: 31332381).
SS-31 (Elamipretide): Mitochondria-targeted tetrapeptide that stabilizes cardiolipin structure, reducing its ability to promote protein aggregation. Phase 3 trials in Barth syndrome (NCT03098797) demonstrated cardiac improvement and established CNS safety. SS-31 does not cross the BBB efficiently, requiring intrathecal delivery for neurological applications.
PINK1 kinase activators: Kinetin triphosphate (KTP, a neo-substrate for PINK1) enhances Parkin recruitment and accelerates mitophagy of PHB2-compromised mitochondria. In PINK1-G309D patient fibroblasts, KTP restores mitophagy to 60% of wild-type levels (PMID: 28082375, Hertz et al., Nat Chem Biol 2013).

Hypothesis 1: Galectin-3 as a Universal Sensor-Dependent Cross-Seeding Platform at Damaged Endo/Lysosomal Membranes
Mechanism
Galectin-3 (LGALS3) functions as a "damage scaffold" that simultaneously recruits multiple aggregation-prone proteins (Aβ42, α-synuclein, TDP-43) to ruptured endolysosomal membranes, creating a localized high-concentration environment that favors cross-nucleation.

The presented hypotheses are mechanistically interesting but pre-clinical, occupying an intermediate translational readiness level between basic discovery and therapeutic development.
