COG4, SEC38, Cog4p
The protein encoded by this gene is a component of an oligomeric protein complex involved in the structure and function of the Golgi apparatus. Defects in this gene may be a cause of congenital disorder of glycosylation type IIj. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Aug 2010] (from

The 1.9 A crystal structure of a Cog4 C-terminal fragment, was determined. Arg 729 is found to occupy a key position at the center of a salt bridge network, thereby stabilizing Cog4's small C-terminal domain.
Study shows that the SM protein, Sly1, interacts directly with the conserved oligomeric Golgi (COG) tethering complex; Sly1-COG interaction is mediated by the Cog4 subunit, which also interacts with Syntaxin 5 through a different binding site.
