The protein encoded by this gene is a peripheral membrane protein localized to the trans-Golgi network. It is sensitive to brefeldin A. This encoded protein contains a GRIP domain which is thought to be used in targeting. Alternative splicing results in multiple transcript variantsSynonyms: CLL-associated antigen KW-11, CTCL tumor antigen se1-1, GRIP and coiled-coil domain-containing protein 2, Golgi coiled-coil protein GCC185, KIAA0336, KW-11, NY-REN-5, RANBP2L4, Ran-binding protein 2-like 4, Renal carcinoma antigen NY-REN-5, se1-1
