Background Information

COPII-coated vesicles mediate anterograde transport from the ER to the Golgi apparatus. COPII is composed of three parts: two coat protein complexes (Sec23/24 complex and Sec13/31 complex) and one small GTP-binding protein, Sar1 (PMID: 9568718). Sec31 subunit of the coat complex has been shown to be essential for vesicle formation and ER-Golgi transport (PMID: 10788476). Two mammalian homologues of yeast sec31p, Sec31A and Sec31B, share about 40% amino acid identity. Sec31A transcripts are ubiquitously and abundantly expressed.
