Golph3Golgi phosphoprotein 3 is a human protein encoded by GOLPH3 gene. It is a peripheral membrane protein of the Golgi that probably has a regulatory role in Golgi trafficking.Clinical significanceGolph 3 expression is associated with poor prognosis of various cancers of gastrointestinal tract, such as gastric and esophageal [squamous cell carcinoma]. Higher expression of GOLPH3 is reported to be associated with greater sensitivity of colorectal cancer to Fluorouracil therapy.
