Summaries for SAR1B Gene

Entrez Gene Summary for SAR1B Gene

  • 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]

GeneCards Summary for SAR1B Gene

SAR1B (Secretion Associated Ras Related GTPase 1B) is a Protein Coding gene. Diseases associated with SAR1B include Chylomicron Retention Disease and Hypobetalipoproteinemia. Among its related pathways are Protein processing in endoplasmic reticulum and Metabolism. GO annotations related to this gene include GTP binding and signal transducer activity. An important paralog of this gene is SAR1A.

UniProtKB/Swiss-Prot for SAR1B Gene

  • Involved in transport from the endoplasmic reticulum to the Golgi apparatus. Activated by the guanine nucleotide exchange factor PREB. Involved in the selection of the protein cargo and the assembly of the COPII coat complex.

  • Chylomicron retention disease (CMRD) [MIM:246700]: An autosomal recessive disorder of severe fat malabsorption associated with failure to thrive in infancy. The condition is characterized by deficiency of fat-soluble vitamins, low blood cholesterol levels, and a selective absence of chylomicrons from blood. Affected individuals accumulate chylomicron-like particles in membrane-bound compartments of enterocytes, which contain large cytosolic lipid droplets. {ECO:0000269 PubMed:12692552, ECO:0000269 PubMed:17309654, ECO:0000269 PubMed:19274794}.
