General description

Golph3 (Golgi phosphoprotein 3), also known as coat protein GPP34, is a peripheral membrane protein of the Golgi stack, that localizes to the trans-Golgi network. It is an oncogene that is commonly targeted for amplification in human cancer and in cancer cell lines.

Immunogen

peptide corresponding to the N-terminal region of human Golph3, conjugated to KLH. The corresponding sequence is identical in mouse, rat, monkey and bovine.

Application

Anti-Golph3 (N-terminal) antibody produced in rabbit has been used in:
  • immunoprecipitation
  • immunofluorescence
  • immunoblotting

Biochem/physiol Actions

Golph3 (Golgi phosphoprotein 3) is important for Golgi trafficking and morphology by interacting with the unconventional myosin MYO18A, linking Golgi membranes to the actin cytoskeleton. It is a phosphatidylinositol-4-phosphate (PtdIns(4)P binding protein required for Golgi function. GOLPH3 overexpression is correlated with hyperactivation of mTOR signaling, in human cells.

Physical form

Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide.

Vesicle budding for Golgi-to-plasma membrane trafficking is a key step in secretion. Proteins that induce curvature of the Golgi membrane are predicted to be required, by analogy to vesicle budding from other membranes. Here, we demonstrate that GOLPH3, upon binding

Genome-wide copy number analyses of human cancers identified a frequent 5p13 amplification in several solid tumour types, including lung (56%), ovarian (38%), breast (32%), prostate (37%) and melanoma (32%). Here, using integrative analysis of a genomic profile of the region

Golgi membranes, from yeast to humans, are uniquely enriched in phosphatidylinositol-4-phosphate (PtdIns(4)P), although the role of this lipid remains poorly understood. Using a proteomic lipid-binding screen, we identify the Golgi protein GOLPH3 (also called GPP34, GMx33, MIDAS, or yeast Vps74p)

Upon DNA damage, cells activate the DNA damage response (DDR) to coordinate proliferation and DNA repair. Dietary, metabolic, and environmental inputs are emerging as modulators of how DNA surveillance and repair take place. Lipids hold potential to convey these cues
