POMT1 - protein O-mannosyltransferase 1 Gene
Also Known as RT; LGMD2K; MDDGA1; MDDGB1; MDDGC1; LGMDR11
Species: Homo sapiens
About POMT1
This gene has 77 transcripts (splice variants), 200 orthologues, 3 paralogues and is associated with 10 phenotypes. Broad expression in testis (RPKM 20.7), brain (RPKM 7.5) and 25 other tissues.
Summary
The protein encoded by this gene is an O-mannosyltransferase that requires interaction with the product of the POMT2 gene for enzymatic function. The encoded protein is found in the membrane of the endoplasmic reticulum. Defects in this gene are a cause of Walker-Warburg syndrome (WWS) and limb-girdle muscular dystrophy type 2K (LGMD2K). Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Oct 2008]
