PIGX Gene

HGNC Family Phosphatidylinositol glycan anchor biosynthesis (PIG)
Name phosphatidylinositol glycan anchor biosynthesis, class X
Description 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]
Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nWithin the endoplasmic reticulum, a group of multitransmembrane glycosyltransferases mediates important modifications, including the addition of mannose residues to glycoproteins and glycosylphosphatidylinositol (GPI) anchor precursors. One key component of this system is PIG-X—a non-catalytic, 252–amino acid, type I transmembrane protein with a large lumenal domain—that forms a complex with the catalytic subunit PIG-M of glycosylphosphatidylinositol-mannosyltransferase I (GPI-MT-I). The primary role of PIG-X is to stabilize PIG-M, as evidenced by the dramatic decrease in PIG-M expression (<10%) observed when PIG-X is absent, thereby ensuring proper addition of the first mannose in the GPI-anchor precursor. Furthermore, the identification of a yeast homolog, Pbn1p, which supports analogous enzymatic activity, reinforces the evolutionary conservation and essential nature of PIG-X in the biosynthesis of GPI anchors."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Hisashi Ashida, Yeongjin Hong, Yoshiko Murakami, et al.
