1/1000. Predicted molecular weight: 45 kDa.
FunctionUnknown. Cellular response protein to viral infection.
Tissue specificityWidely expressed. Highly expressed in colon, prostate, trachea and stomach. Expressed at lower level in testis, muscle, lymphoid tissues, white blood cells and spleen. Predominantly expressed by cells of the epithelial lineage. Expressed at low level in normal liver. Expression significantly increases in virus (HBV, HCV) infected liver. Expression does not increase in liver disease due to non-viral causes (alcohol-induced liver disease, autoimmune hepatitis). Increased expression in hepatocytes appears to be a general feature of advanced liver disease. In liver tissue from patients with adult giant-cell hepatitis (GCH), it is strongly expressed in hepatocyte-derived syncitial giant cells. Constitutively expressed by biliary epithelial cells but not by hepatocytes.
Sequence similaritiesBelongs to the GOLM1/CASC4 family.
Post-translational modificationsGlycosylated. Phosphorylation sites are present in the extracelllular medium.
Cellular localizationGolgi apparatus > cis-Golgi network membrane. Early Golgi. Cycles via the cell surface and endosomes upon lumenal pH disruption.
