FN3K | GeneID:64122 | Homo sapiens

Gene Summary

[ - ] NCBI Entrez Gene

Gene ID 64122 Official Symbol FN3K
Locus N/A Gene Type protein-coding
Full Name fructosamine 3 kinase
Description fructosamine 3 kinase
Chromosome 17q25.3
Also Known As fructosamine-3-kinase
Summary 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 (Delpierre et al., 2000 [PubMed 11016445]).[supplied by OMIM]
