CHCHD8 is a mitochondrial protein also known as Coiled-Coil-Helix-Coiled-Coil-Helix Domain Containing 8. It features a molecular mass of approximately 23 kDa. Researchers find CHCHD8 expressed predominantly in the mitochondria of skeletal muscle heart and brain tissues. This protein contributes to mitochondrial function and organization assisting in the maintenance of cellular energy and balance.

Biological function summary

CHCHD8 acts as a component of the mitochondrial intermembrane space bridging complex (MICOS). This complex plays a pivotal role in maintaining mitochondrial architecture and integrity. CHCHD8 contributes to the folding and assembly of other mitochondrial proteins. Its interactions within the MICOS complex reveal its influence on cristae morphology which is essential for the proper function of the electron transport chain.

Pathways

CHCHD8 takes part in mitochondrial biogenesis and cellular respiration pathways. These pathways are important for cell energy production and metabolic balance. CHCHD8 participates alongside proteins such as CHCHD3 and SAMM50 in regulating the structure and function of mitochondria integrating signals related to energy requirements and reactive oxygen species handling.

CHCHD8 has a connection with neuromuscular diseases and mitochondrial myopathies. Mutations or disruptions in CHCHD8 can lead to impaired mitochondrial function contributing to disease pathology. CHCHD8 is linked with CHCHD10 another protein implicated in similar disorders highlighting their combined importance in mitochondrial and neuromuscular health.
