VPS74/YDR372C Summary Help

Standard Name VPS74 1
Systematic Name YDR372C
Alias API1 2 , MNN3 3 , 4
Feature Type ORF, Verified
Description Golgi phosphatidylinositol-4-kinase effector and PtdIns4P sensor; interacts with the cytosolic domains of cis and medial glycosyltransferases, and in the PtdIns4P-bound state mediates the targeting of these enzymes to the Golgi; interacts with the catalytic domain of Sac1p, the major cellular PtdIns4P phosphatase, to direct dephosphosphorylation of the Golgi pool of PtdIns4P; tetramerization required for function; ortholog of human GOLPH3/GPP34/GMx33 (5, 6, 7, 8, 9)
Name Description Vacuolar Protein Sorting 1
