Protein Information
Synonyms FCMD
Function Catalyzes the transfer of CDP-ribitol to the distal N- acetylgalactosamine of the phosphorylated O-mannosyl trisaccharide (N-acetylgalactosamine-beta-3-N-acetylglucosamine-beta-4- (phosphate-6-)mannose), a carbohydrate structure present in alpha- dystroglycan (DAG1) (PubMed:17034757, PubMed:25279699, PubMed:26923585, PubMed:29477842). This constitutes the first step in the formation of the ribitol 5-phosphate tandem repeat which links the phosphorylated O-mannosyl trisaccharide to the ligand binding moiety composed of repeats of 3-xylosyl-alpha-1,3- glucuronic acid-beta-1 (PubMed:17034757, PubMed:25279699, PubMed:26923585, PubMed:29477842). Required for normal location of POMGNT1 in Golgi membranes, and for normal POMGNT1 activity (PubMed:17034757). May interact with and reinforce a large complex encompassing the outside and inside of muscle membranes (PubMed:25279699). Could be involved in brain development (Probable).
Cellular Location Golgi apparatus membrane; Single-pass type II membrane protein. Cytoplasm {ECO:0000250|UniProtKB:Q8R507}. Nucleus {ECO:0000250|UniProtKB:Q8R507}. Note=In retinal tissue, does not localize with the Golgi apparatus. {ECO:0000250|UniProtKB:Q8R507}
Tissue Location Expressed in the retina (at protein level) (PubMed:29416295). Widely expressed with highest expression in brain, heart, pancreas and skeletal muscle (PubMed:11115853) Expressed at similar levels in control fetal and adult brain (PubMed:11115853). Expressed in migrating neurons, including Cajar-Retzius cells and adult cortical neurons, as well as hippocampal pyramidal cells and cerebellar Purkinje cells (PubMed:11115853). No expression observed in the glia limitans, the subpial astrocytes (which contribute to basement membrane formation) or other glial cells (PubMed:11115853)

The protein encoded by this gene is a putativetransmembrane protein that is localized to the cis-Golgicompartment, where it may be involved in the glycosylation ofalpha-dystroglycan in skeletal muscle. The encoded protein isthought to be a glycosyltransferase and could play a role in braindevelopment. Defects in this gene are a cause of Fukuyama-typecongenital muscular dystrophy (FCMD), Walker-Warburg syndrome(WWS), limb-girdle muscular dystrophy type 2M (LGMD2M), and dilatedcardiomyopathy type 1X (CMD1X). Alternatively spliced transcriptvariants have been found for this gene.
