PIGX phosphatidylinositol glycan anchor biosynthesis class X

Gene ID: 54965, updated on 17-Sep-2024
Gene type: protein coding
Also known as: PIG-X

Summary

This gene encodes a type I transmembrane protein in the endoplasmic reticulum (ER). The protein is an essential component of glycosylphosphatidylinositol-mannosyltransferase I, which transfers the first of the four mannoses in the GPI-anchor precursors during GPI-anchor biosynthesis. Studies in rat indicate that the protein is translated from a non-AUG translation initiation site. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]
