GPI-Mannosyltransferase Subunit
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]
Forensic Context
A study in human postmortem prefrontal cortex identified gene modules associated with schizophrenia symptoms, where the PIGX was included in the blue gene module, which is located in the 3q29 deletion region and overlaps with the Multiple Sclerosis signaling pathway [Miyahara et al.
