COG6 (Component Of Oligomeric Golgi Complex 6): COG6 is a crucial component of the COG complex, which is vital for normal Golgi apparatus function and vesicular transport. It plays an important role in maintaining the structure of the Golgi and ensuring correct glycosylation of proteins, an essential post-translational modification. Mutations in COG6 can result in congenital disorders of glycosylation, causing a range of clinical manifestations including developmental delays and neurological issues.
