Structure

TIMM10 is a small mitochondrial intermembrane space (IMS) chaperone protein. Key structural features: [@neuroinflammation2015]

• Zinc-finger domain: Two zinc-binding motifs (CX2C, CX3H) that coordinate Zn2+ ions
• α-helical structure: Forms a rod-like scaffold for protein interactions
• Dimer formation: Functions as a homodimer or heterodimer with TIMM10B
• Tim9-Tim10 complex: Forms a hexameric chaperone complex (Tim9-Tim10)2-Tim10 [1]

The zinc-finger motifs are essential for: [@cellular2018]

• Stabilizing the chaperone complex
• Interacting with hydrophobic transmembrane domains of incoming proteins
• Preventing aggregation in the aqueous IMS

Normal Function

TIMM10 is essential for mitochondrial protein import via the TIM22 complex: [@therapeutic2017]

Normal Function

TIMM10 is essential for mitochondrial protein import via the TIM22 complex: [@therapeutic2017]

Substrate recognition: Recognizes hydrophobic carrier proteins in the IMS

Chaperone function: Prevents aggregation of hydrophobic proteins

Substrate delivery: Guides carrier proteins to the TIM22 translocase

Membrane insertion: Facilitates insertion into the inner mitochondrial membrane

Key substrates include: [@biomarkers2016]

• Metabolite carriers: UCP, PiC, CitC, AAC
• Ion channels: MCU, LetM1
• Other IMS proteins: Small IMS proteins

In [neurons](/entities/neurons), TIMM10 supports:

• Respiratory chain assembly: Import of complex I-V components
• Mitochondrial DNA maintenance: Import of proteins for mtDNA replication
• Calcium signaling: Import of mitochondrial calcium uniporters [2]

Role in Disease

Amyotrophic Lateral Sclerosis

• Reduced TIMM10 expression in ALS motor neurons contributes to mitochondrial dysfunction [3]
• Mitochondrial protein import defects are a hallmark of ALS
• TIMM10 mutations may modify disease progression

Parkinson's Disease

• Impaired mitochondrial protein import in PD models [4]
• The PINK1/Parkin pathway regulates TIMM10 turnover
• TIMM10 dysfunction contributes to Complex I deficiency

Mitochondrial Disorders

• TIMM10 deficiency causes severe encephalomyopathy [5]
