CCDC91 Proteins

Protein Information

CCDC91 (Coiled-Coil Domain-Containing 91) is a gene located on chromosome 12q24.31 that encodes a protein involved in vesicle-mediated transport and Golgi function. The CCDC91 protein contains coiled-coil domains, which facilitate protein-protein interactions necessary for its role in the secretory pathway. Specifically, CCDC91 is a component of the Golgi-associated retrograde protein (GARP) complex, which is essential for the recycling of transport vesicles from endosomes to the trans-Golgi network (TGN). Research has revealed that CCDC91 is crucial for maintaining Golgi structure and function and is involved in the sorting and trafficking of proteins and lipids within the cell. The protein's interactions with other components of the vesicular transport machinery enable the efficient movement of cargo between organelles, which is critical for various cellular processes, including secretion, endocytosis, and lysosomal degradation. Mutations or dysregulation of CCDC91 can disrupt these processes, potentially leading to diseases associated with vesicle trafficking defects, such as certain neurodegenerative disorders and cancer.
