GCC1  GRIP and coiled-coil domain-containing protein 1 is a protein that in humans is encoded by the "GCC1" gene. The protein encoded by this gene is a peripheral membrane protein. It is sensitive to brefeldin A. This encoded protein contains a GRIP domain which is thought to be used in targeting. It may play a role in the organization of trans-Golgi network subcompartment involved with membrane transport. GCC1 has been shown to interact with TRIM29.
