🔬 Protein Info
Gene SymbolNPTX1
AliasesNeuronal Pentraxin 1
Chromosome17q21.31.
FunctionNeuronal Pentraxin 1 (NPTX1) is a member of the pentraxin family of proteins, which are characterized by their ability to bind to phosphatidylserine and apoptotic cells.
Molecular Weight47 kDa
Amino Acids430 aa
Pathwaysoxidative stress response
Ensembl IDENSG00000143157
GeneCardsNPTX1
Human Protein AtlasNPTX1
CSF levelsElevated NPTX1 levels in cerebrospinal fluid correlate with disease severity as measured by MMSE scores and CSF tau/phospho-tau levels (Chen et al., 2019; Song et al., 2021)
Synaptic lossNPTX1 is released during synaptic degeneration, making it a marker of synaptic integrity (Yin et al., 2020)
Disease progressionLongitudinal studies show that NPTX1 can predict conversion from mild cognitive impairment (MCI) to AD with moderate accuracy (AUC ~0.75-0.80)
Pathology correlationNPTX1 levels correlate with amyloid-beta plaque burden and neurofibrillary tangle density in postmortem brain tissue
CSF elevationsMultiple studies have demonstrated elevated CSF NPTX1 in PD patients compared to healthy controls (Ma et al., 2018)
Associated DiseasesInflammation, Neuroinflammation
InteractionsSERPINA3, CTSB, CTSD, PDGFRB, SYNAPSE, CHI3L1
