Function | Fructosamine-3-kinase involved in protein deglycation by mediating phosphorylation of fructoselysine residues on glycated proteins, to generate fructoselysine-3 phosphate (PubMed:11016445, PubMed:11522682, PubMed:11975663). Fructoselysine-3 phosphate adducts are unstable and decompose under physiological conditions (PubMed:11522682, PubMed:11975663). Involved in intracellular deglycation in erythrocytes (PubMed:11975663). Involved in the response to oxidative stress by mediating deglycation of NFE2L2/NRF2, glycation impairing NFE2L2/NRF2 function (By similarity). Also able to phosphorylate psicosamines and ribulosamines (PubMed:14633848). |
Tissue Location | Widely expressed (PubMed:11522682). Expressed in erythrocytes (PubMed:11016445). |

Background
FN3K catalyzes phosphorylation of fructosamines formed by glycation, the nonenzymatic reaction of glucose with primary amines followed by Amadori rearrangement. Phosphorylation of fructosamines may initiate metabolism of the modified amine and result in deglycation of glycated proteins. Human and mouse FN3K share 86% amino acid identity. GENE Purified FN3K catalyzes ATP-dependent phosphorylation of a synthetic fructosamine, 1-deoxy-1-morpholinofructose (DMF). Recombinant mouse and human FN3K, expressed in E. coli, catalyze phosphorylation of DMF, fructoselysine, fructoseglycine, and fructose in order of decreasing affinity. They also phosphorylate glycated lysozyme, but not unmodified lysozyme. In addition to ATP, FN3K can utilize GTP, CTP, and UTP as phosphate donors.
