POMGNT1 - protein O-linked mannose N-acetylglucosaminyltransferase 1 (beta 1,2-) Gene
Also Known as MEB; RP76; GNTI.2; LGMD2O; GnT I.2; LGMDR15; MGAT1.2; gnT-I.2
Species: Homo sapiens
About POMGNT1
This gene has 50 transcripts (splice variants), 202 orthologues, 1 paralogue and is associated with 12 phenotypes. Ubiquitous expression in heart (RPKM 23.4), thyroid (RPKM 21.0) and 25 other tissues.
Summary
This gene encodes a type II transmembrane protein that resides in the Golgi apparatus. It participates in O-mannosyl glycosylation and is specific for alpha linked terminal mannose. Mutations in this gene may be associated with muscle-eye-brain disease and several congenital muscular dystrophies. Alternatively spliced transcript variants that encode different protein isoforms have been described. [provided by RefSeq, Feb 2014]
