Description General description Golgi membrane protein 1 (UniProt: Q8NBJ4; also known as Golgi membrane protein GP73, Golgi phosphoprotein 2) is encoded by the GOLM1 (also known as C9orf155, GOLPH2, PSEC0242, UNQ686/PRO1326) gene (Gene ID: 51280) in human. GP73 is a single-pass type II membrane protein that cycles via the cell surface and endosomes upon lumenal pH disruption. It is constitutively expressed in cells of epithelial lineage. It is highly expressed in colon, prostate, trachea, and stomach. In normal liver it is expressed at low level, but the expression is significantly increased in response to viral (HBV, HCV) infections, but not in diseases of non-viral origin. Its levels are also shown to be elevated in hepatocellular carcinoma (HCC) and in invasive breast cancer. GP73 is reported to promote HCC invasion by activation of matrix metalloproteinase-13 (MMP-13). Two isoforms of GP73 have been described that are produced by alternative initiation.
