Gene: Sar1b (secretion associated, Ras related GTPase 1B) Rattus norvegicus
Symbol: Sar1b
Name: secretion associated, Ras related GTPase 1B
CRRD ID: 1305590
Description: Predicted to have GTPase activity. Predicted to be involved in several processes, including endoplasmic reticulum to Golgi vesicle-mediated transport; intracellular protein transport; and regulation of intracellular transport. Predicted to localize to COPII vesicle coat and endoplasmic reticulum exit site. Human ortholog(s) of this gene implicated in chylomicron retention disease. Orthologous to human SAR1B (secretion associated Ras related GTPase 1B); PARTICIPATES IN Endoplasmic Reticulum-associated degradation pathway; INTERACTS WITH acetamide; bisphenol A; buspirone.
Type: protein-coding
Also known as: GTP-binding protein SAR1b; LOC287276; SAR1 gene homolog B; SAR1 gene homolog B (S. cerevisiae); SAR1 homolog B; SAR1 homolog B (S. cerevisiae); SAR1a gene homolog 2; SAR1a gene homolog 2 (S. cerevisiae); SARA1B; Sara2
