Summary
PIGV (phosphatidylinositol glycan anchor biosynthesis class V, HGNC:26031) is a protein-coding gene on chromosome 1p36.11, encoding GPI alpha-1,6-mannosyltransferase 2 (Q9NUD9). Alpha-1,6-mannosyltransferase that catalyzes the transfer of the second mannose, via an alpha-1,6 bond, from a dolichol-phosphate-mannose (Dol-P-Man) to a 2-acyl-6-(alpha-D-mannosyl-(1->4)-alpha-D-glucosaminyl)-1-(1-radyl,2-acyl-sn-glycero-3-phospho)-1D-myo-inositol (also termed….
This gene encodes a mannosyltransferase enzyme involved in the biosynthesis of glycosylphosphatidylinositol (GPI). GPI is a complex glycolipid that functions as a membrane anchor for many proteins and plays a role in multiple cellular processes including protein sorting and signal transduction. The encoded protein is localized to the endoplasmic reticulum and transfers the second mannose to the GPI backbone. Mutations in this gene are associated with hyperphosphatasia cognitive disability syndrome. Alternatively spliced transcript variants have been observed for this gene.

Function. Alpha-1,6-mannosyltransferase that catalyzes the transfer of the second mannose, via an alpha-1,6 bond, from a dolichol-phosphate-mannose (Dol-P-Man) to a 2-acyl-6-(alpha-D-mannosyl-(1->4)-alpha-D-glucosaminyl)-1-(1-radyl,2-acyl-sn-glycero-3-phospho)-1D-myo-inositol (also termed H2) intermediate to generate a 2-acyl-6-[alpha-D-mannosyl-(1->6)-alpha-D-mannosyl-(1->4)-alpha-D-glucosaminyl]-1-(1-radyl,2-acyl-sn-glycero-3-phospho)-1D-myo-inositol (also termed H3) and participates in the seventh step of the glycosylphosphatidylinositol-anchor biosynthesis. May also transfer the second mannose on a 2-acyl-6-[2-phosphoethanolamine-alpha-D-mannosyl-(1->4)-alpha-D-glucosaminyl]-1-(1-radyl,2-acyl-sn-glycero-3-phospho)-1D-myo-inositol (also termed H5), but less effectively.
Subcellular location. Endoplasmic reticulum membrane.
Post-translational modifications. Not N-glycosylated.
Disease relevance. Hyperphosphatasia with impaired intellectual development syndrome 1 (HPMRS1) [MIM:239300] A severe syndrome characterized by elevated serum alkaline phosphatase, severe intellectual disability, seizures, hypotonia, facial dysmorphism, and hypoplastic terminal phalanges. The disease is caused by variants affecting the gene represented in this entry.
Pathway. Glycolipid biosynthesis; glycosylphosphatidylinositol-anchor biosynthesis.
Similarity. Belongs to the PIGV family.
