COG6 (Component Of Oligomeric Golgi Complex 6): COG6 is a key part of the COG complex, which is essential for normal Golgi function and vesicular trafficking. It plays a vital role in maintaining Golgi structure and ensuring proper glycosylation of proteins, a critical post-translational modification. Mutations in COG6 can cause congenital disorders of glycosylation, leading to a variety of clinical symptoms such as developmental delay and neurological problems.
