As a key regulator of glucose influx into the hexosamine pathway, the GFPT1 protein plays a key role in controlling the availability of protein N- and O-linked glycosylation precursors. In addition, GFPT1 is involved in the regulation of circadian expression of clock genes BMAL1 and CRY1 and contributes to the complex regulation of cytoplasmic UDP-GlcNAc metabolic fluctuations. GFPT1 Protein, Human is the recombinant human-derived GFPT1 protein, expressed by E. coli , with tag free.
