Description
Fructosamine-3-kinase involved in protein deglycation by mediating phosphorylation of fructoselysine residues on glycated proteins, to generate fructoselysine-3 phosphate (PubMed: 11016445, PubMed: 16819943). Fructoselysine-3 phosphate adducts are unstable and decompose under physiological conditions (By similarity). Involved in intracellular deglycation in erythrocytes and pancreatic islets (PubMed: 16819943, PubMed: 20009024). Involved in the response to oxidative stress by mediating deglycation of NFE2L2/NRF2, glycation impairing NFE2L2/NRF2 function (PubMed: 31398338). Also able to phosphorylate psicosamines and ribulosamines (By similarity)
