Overview
GFAT 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: Carbohydrate Metabolism - amino sugar and nucleotide sugar; EC 2.6.1.16; Amino Acid Metabolism - alanine, aspartate and glutamate; Transferase
Cellular Component: cytosol
Molecular Function: amino acid binding; glutamine-fructose-6-phosphate transaminase (isomerizing) activity; carbohydrate binding
Biological Process: dolichol-linked oligosaccharide biosynthetic process; unfolded protein response; glucosamine biosynthetic process; glutamine metabolic process; post-translational protein modification; fructose 6-phosphate metabolic process; carbohydrate biosynthetic process; protein homotetramerization; response to sucrose stimulus; cellular protein metabolic process; unfolded protein response, activation of signaling protein activity; cellular response to insulin stimulus; energy reserve metabolic process; UDP-N-acetylglucosamine biosynthetic process; protein amino acid N-linked glycosylation via asparagine; circadian regulation of gene expression; negative regulation of glycogen biosynthetic process
