Summary: 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]

Exome-Wide Association Study Identifies FN3KRP and PGP as New Candidate Longevity Genes.
Title: Exome-Wide Association Study Identifies FN3KRP and PGP as New Candidate Longevity Genes.
Studies provide evidence that Fn3KRP possesses an ATP-binding domain that is structurally related to that of both the aminoglycoside kinases and eukaryotic protein kinases.
Title: Mapping of the ATP-binding domain of human fructosamine 3-kinase-related protein by affinity labelling with 5'-[p-(fluorosulfonyl)benzoyl]adenosine.
FN3KRP phosphorylates meglumine to produce meglumine-4-phosphate.
Title: Fructosamine-3-kinase-related-protein phosphorylates glucitolamines on the C-4 hydroxyl: novel substrate specificity of an enigmatic enzyme.
These data suggest that FN3K and FN3KRP act as protein repair enzymes and are expressed constitutively in human cells independently of some of the variables altered in the diabetic state.
Title: The expression of the genes for fructosamine-3-kinase and fructosamine-3-kinase-related protein appears to be constitutive and unaffected by environmental signals.
Enzyme is a constitutive "housekeeping" gene and that ig plays an important role in cell metabolism, possibly as a deglycating enzyme.
Title: Some clues as to the regulation, expression, function, and distribution of fructosamine-3-kinase and fructosamine-3-kinase-related protein.
In this paper we propose a resolution of both these quandaries by proposing that fructosamine-6-phosphates are deglycated by phosphorylation to fructosamine-3,6-bisphosphates catalyzed by FN3KRP and/or possibly FN3K.
Title: Fructosamine-6-phosphates are deglycated by phosphorylation to fructosamine-3,6-bisphosphates catalyzed by fructosamine-3-kinase (FN3K) and/or fructosamine-3-kinase-related-protein (FN3KRP).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: VALIDATED

Description

Transcript Variant: This variant (2) contains an alternate 5' exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
