Summaries for FN3KRP Gene

Entrez Gene Summary for FN3KRP Gene

  • A high concentration of glucose can result in non-enzymatic oxidation of proteins by reaction of glucose and lysine residues (glycation). Proteins modified in this way are less active or functional. This gene encodes an enzyme which catalyzes the phosphorylation of psicosamines and ribulosamines compared to the neighboring gene which encodes a highly similar enzyme, fructosamine-3-kinase, which has different substrate specificity. The activity of both enzymes may result in deglycation of proteins to restore their function. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2012]

GeneCards Summary for FN3KRP Gene

FN3KRP (Fructosamine 3 Kinase Related Protein) is a Protein Coding gene. GO annotations related to this gene include kinase activity. An important paralog of this gene is FN3K.

UniProtKB/Swiss-Prot for FN3KRP Gene

  • Phosphorylates psicosamines and ribulosamines, but not fructosamines, on the third carbon of the sugar moiety. Protein-bound psicosamine 3-phosphates and ribulosamine 3-phosphates are unstable and decompose under physiological conditions. Thus phosphorylation leads to deglycation.
