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 legionellosis. GO annotations related to this gene include GTP binding and GTPase activity. An important paralog of this gene is SAR1A.

UniProtKB/Swiss-Prot: SAR1B_HUMAN, Q9Y6B6
Function: 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. Note=The disease is caused by mutations affecting the gene represented in this
    entry
