SAR1 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G186030 (symbol SAR1, also known as TtSAR1) on durum wheat chromosome 7A encodes a small GTP-binding protein of the SAR1 family, a component of the COPII vesicle coat. The product exhibits GTPase, GTP-binding, phospholipase activator and G protein activities. The gene is associated with ER-to-Golgi transport, vesicle organisation, membrane organisation, secretion, intracellular protein transport, detoxification and cell division. It is linked to localisation at the ER exit site, COPII vesicle coat, Golgi membrane, ER membrane, cilial membrane, microtubule-organising centre and spindle. Studies of related genes in other species connect the SAR1 family to root length and seed germination traits.
