Controls the flux of glucose into the hexosamine pathway. Most likely involved in regulating the availability of precursors for N- and O-linked glycosylation of proteins. Homotetramer (Potential). Isoform 1 is predominantly expressed in skeletal muscle. Not expressed in brain. Seems to be selectively expressed in striated muscle. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: Amino Acid Metabolism - alanine, aspartate and glutamate; Carbohydrate Metabolism - amino sugar and nucleotide sugar; EC 126.96.36.199; Transferase
