Protein damage, repair and proteolysis.
Athens, Greece. In Mol Aspects Med, 2014
With regard to protein repair, only few repair mechanisms have been evidenced including the reduction of methionine sulfoxide residues by the methionine sulfoxide reductases, the conversion of isoaspartyl residues to L-aspartate by L-isoaspartate methyl transferase and deglycation by phosphorylation of protein-bound fructosamine by fructosamine-3-kinase.
Enzymatic repair of Amadori products.
Brussels, Belgium. In Amino Acids, 2012
Fructosamine-3-kinase (FN3K), an enzyme found in mammals and birds, phosphorylates fructosamines on the third carbon of their sugar moiety, making them unstable and causing them to detach from proteins.
Race-ethnic differences in the association of genetic loci with HbA1c levels and mortality in U.S. adults: the third National Health and Nutrition Examination Survey (NHANES III).
Boston, United States. In Bmc Med Genet, 2011
We tested the hypotheses that there is race-ethnic variation in 1) HbA1c-associated risk allele frequencies (RAFs) for SNPs near SPTA1, HFE, ANK1, HK1, ATP11A, FN3K, TMPRSS6, G6PC2, GCK, MTNR1B; 2) association of SNPs with HbA1c and 3) association of SNPs with mortality.
Identification of a gene-expression signature for predicting lymph node metastasis in patients with early stage cervical carcinoma.
Guangzhou, China. In Cancer, 2011
RESULTS: A gene-expression signature for predicting PLNM was developed in patients from the training group, including 11 genes: ribosomal protein L35 (RPL35); thymosin β 10 (TMSB10); tyrosine 3-mono-oxytenase/tryptophan 5-mono-oxygenase activation protein, ζ polypeptide (YWHAZ); biotinidase (BTD); lactate dehydrogenase A (LDHA); glucuronidase β (GUSB); superoxide dismutase 2 (SOD2); nuclear receptor subfamily 3, group C, member 2 (NR3C2); fructosamine 3 kinase (FN3K); x-ray repair cross-complementing 4 (XRCC4); and wingless-type mouse mammary tumor virus integration site family member 2 (WNT2).
Enzymatic deglycation--a new paradigm or an epiphenomenon?
United States. In Biochem Soc Trans, 2003
Following the discovery of FN3K (fructosamine 3-kinase), and more recently of FN3KRP (FN3K-related protein), research in our laboratory has been focused on testing the enzymatic deglycation hypothesis and investigating the roles of FN3K and FN3KRP.
