About SAR1B

Cytogenetic location: 5q31.1 Genomic coordinates (GRCh38): 5:134,601,149-134,632,828 (from NCBI)

This gene has 11 transcripts (splice variants), 119 orthologues, 30 paralogues and is associated with 2 phenotypes. Ubiquitous expression in liver (RPKM 17.3), small intestine (RPKM 16.1) and 25 other tissues.

Summary

The protein encoded by this gene is a small GTPase that acts as a homodimer. The encoded protein is activated by the guanine nucleotide exchange factor PREB and is involved in protein transport from the endoplasmic reticulum to the Golgi. This protein is part of the COPII coat complex. Defects in this gene are a cause of chylomicron retention disease (CMRD), also known as Anderson disease (ANDD). Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Mar 2010]
