DESCRIPTION

Also known as SC31B_HUMAN, SEC31B, SEC31L2. As a component of the coat protein complex II (COPII), may function in vesicle budding and cargo export from the endoplasmic reticulum. COPII is composed of at least 5 proteins: the SEC23/24 complex, the SEC13/31 complex and SAR1. SEC13 and SEC31 make a 2:2 tetramer that forms the edge element of the COPII outer coat. The tetramer self-assembles in multiple copies to form the complete polyhedral cage. Interacts (via WD 8) with SEC13 (By similarity). Interacts with SEC31A.
