Identification
HMDB Protein ID CDBP03785
Secondary Accession Numbers Not Available
Name GTP-binding protein SAR1a
Description Not Available
Synonyms
  1. COPII-associated small GTPase
Gene Name SAR1A
Protein Type Enzyme
Biological Properties
General Function Involved in GTP binding
Specific Function Involved in transport from the endoplasmic reticulum to the Golgi apparatus. Required to maintain SEC16A localization at discrete locations on the ER membrane perhaps by preventing its dissociation. SAR1A-GTP-dependent assembly of SEC16A on the ER membrane forms an organized scaffold defining endoplasmic reticulum exit sites (ERES)
