About MGAT1

Cytogenetic location: 5q35.3 Genomic coordinates (GRCh38): 5:180,784,780-180,815,616 (from NCBI)

This gene has 25 transcripts (splice variants), 249 orthologues and 1 paralogue. Ubiquitous expression in fat (RPKM 30.2), spleen (RPKM 29.9) and 25 other tissues.

Summary

There are believed to be over 100 different glycosyltransferases involved in the synthesis of protein-bound and lipid-bound oligosaccharides. UDP-N-acetylglucosamine:alpha-3-D-mannoside beta-1,2-N-acetylglucosaminyltransferase I is a medial-Golgi enzyme essential for the synthesis of hybrid and complex N-glycans. The protein, encoded by a single exon, shows typical features of a type II transmembrane protein. The protein is believed to be essential for normal embryogenesis. Several variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]
