Protein Name:
Small COPII coat GTPase SAR1A
|
UniprotKB/SwissProt ID: O04834 (O04834)
Gene Name:
SAR1A
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Small GTPase that cycles between an active GTP-bound and an inactive GDP-bound state and mainly functions in vesicle-mediated endoplasmic reticulum (ER) to Golgi transport. The active GTP-bound form inserts into the endoplasmic reticulum membrane where it recruits the remainder of the coat protein complex II/COPII. The coat protein complex II assembling and polymerizing on endoplasmic reticulum membrane is responsible for both the sorting of cargos and the deformation and budding of membranes into vesicles destined to the Golgi
