The product of this gene is a Golgi enzyme catalyzing an essential step in the conversion of oligomannose to complex N-glycans. The enzyme has the typical glycosyltransferase domains: a short N-terminal cytoplasmic domain, a hydrophobic non-cleavable signal-anchor domain, and a C-terminal catalytic domain. Mutations in this gene may lead to carbohydrate-deficient glycoprotein syndrome, type II. The coding region of this gene is intronless. Transcript variants with a spliced 5' UTR may exist, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]
Forensic Context
A longitudinal mRNA expression analysis in post-mortem human blood samples identified the MGAT2 as a protein-coding gene with a negative coefficient in a post-mortem interval (PMI) prediction model, where it was included in a down-regulated expression cluster [Antiga et al. DOI:10.1038/s41598-021-96095-z].
