Target

  • 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.
  • Tissue specificity

    Expressed in many tissues including small intestine, liver, muscle and brain.
  • Involvement in disease

    Defects in SAR1B are the cause of chylomicron retention disease (CMRD) [MIM:246700]; also known as Anderson disease (ANDD). CMRD is 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.
  • Sequence similarities

    Belongs to the small GTPase superfamily. SAR1 family.
  • Cellular localization

    Endoplasmic reticulum membrane. Golgi apparatus > Golgi stack membrane. Associated with the endoplasmic reticulum and Golgi stacks, in particular in the juxta-nuclear Golgi region.
  • Target information above from: UniProt accession Q9Y6B6 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010
    Nucleic Acids Res. 38:D142-D148 (2010) .
