PIG-X

PIG-X / PBN1
PIG-X
SMART accession number:SM00780
Description: Mammalian PIG-X and yeast PBN1 are essential components of glycosylphosphatidylinositol-mannosyltransferase I. These enzymes are involved in the transfer of sugar molecules.
Interpro abstract (IPR013233):

Mammalian PIG-X and yeast PBN1 are essential components of glycosylphosphatidylinositol-mannosyltransferase I [ (PUBMED:15635094) ]. These enzymes are involved in the transfer of sugar molecules. They probably act by stabilizing the mannosyltransferase PIG-M (GPI14 in yeast) [ (PUBMED:15635094) (PUBMED:16418276) ].

GO process:GPI anchor biosynthetic process (GO:0006506)
GO component:endoplasmic reticulum membrane (GO:0005789)
