Golgi phosphoprotein 3 (GOLPH3), a Phosphatidylinositol 4-Phosphate [PI(4)P] effector at the Golgi, is required for several intracellular functions, including Golgi ribbon structure maintenance, Golgi glycosylation and vesicle trafficking. It is amplified in several solid tumor types and its overexpression correlates with poor prognosis. GOLPH3 influences tumorigenesis through (i) regulation of Golgi-to-plasma membrane trafficking; (ii) turnover and glycosylation of cancer-relevant glycoproteins; (iii) influence on DNA damage response and maintenance of genomic stability.

Abstract
Golgi phosphoprotein 3 (GOLPH3), a Phosphatidylinositol 4-Phosphate [PI(4)P] effector at the Golgi, is required for several intracellular functions, including Golgi ribbon structure maintenance, Golgi glycosylation and vesicle trafficking. It is amplified in several solid tumor types and its overexpression correlates with poor prognosis. GOLPH3 influences tumorigenesis through (i) regulation of Golgi-to-plasma membrane trafficking; (ii) turnover and glycosylation of cancer-relevant glycoproteins; (iii) influence on DNA damage response and maintenance of genomic stability.File in questo prodotto:
