CHCHD3 (Coiled-Coil-Helix-Coiled-Coil-Helix Domain Containing Protein 3) is a mitochondrial protein belonging to the CHCHD family, characterized by twin CHCH domains that facilitate protein-protein interactions and structural stability. It plays a critical role in maintaining mitochondrial cristae architecture and function, closely associated with the MICOS (Mitochondrial Contact Site and Cristae Organizing System) complex. This complex ensures proper inner mitochondrial membrane folding, essential for oxidative phosphorylation (OXPHOS) and energy production. CHCHD3 is also implicated in regulating apoptosis, calcium homeostasis, and mitochondrial dynamics, linking its function to cellular metabolism and stress responses.
Dysregulation of CHCHD3 has been observed in neurodegenerative disorders (e.g., Parkinson’s and Alzheimer’s diseases) and cancers, where mitochondrial dysfunction drives pathogenesis. Its interaction with apoptosis-related proteins like OPA1 underscores its role in membrane integrity and cell survival. Recombinant CHCHD3 proteins, typically expressed in *E. coli* or mammalian systems, enable mechanistic studies by mimicking native protein behavior. These engineered proteins retain functional domains, allowing researchers to explore CHCHD3’s structural properties, binding partners, and disease-associated mutations *in vitro*. Such studies are pivotal for developing therapeutic strategies targeting mitochondrial dysfunction. Overall, CHCHD3 is a key regulator of mitochondrial health, with recombinant forms serving as vital tools for unraveling its biological and pathological significance.
