SAR1 — Triticum turgidum subsp. durum

Summary

TRITD3BV1G085610, also known as SAR1, TtARL1D, or ARL1D on durum wheat chromosome 3B, encodes a small GTPase of the SAR1/ARF family, possessing GTPase activity, GTP binding, G protein activity, phospholipase activator activity, and metal binding. It is associated with membrane and vesicle organization, ER-to-Golgi transport, secretion, detoxification, intracellular protein transport, cell division, and protein transport. The gene product localizes to the COPII vesicle coat, ER exit site, Golgi membrane, ER membrane, cilial membrane, microtubule organizing center, and spindle. Studies of related genes in other species link the family to GTPase activity (EC 3.6.5.2).
