== Function ==
[https://www.uniprot.org/uniprot/FN3K_HUMAN FN3K_HUMAN] 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).[UniProtKB:Q9ER35]<ref>PMID:11016445</ref> <ref>PMID:11522682</ref> <ref>PMID:11975663</ref> <ref>PMID:14633848</ref>
