COG6 (Component Of Oligomeric Golgi Complex 6): COG6 is a crucial part of the COG complex, essential for normal Golgi function and vesicular trafficking. It plays a key role in maintaining the Golgi structure and ensuring proper protein glycosylation, a critical post-translational modification. Mutations in COG6 can lead to congenital disorders of glycosylation, resulting in various clinical symptoms such as developmental delays and neurological issues.
