Summary: Riboflavin kinase (RFK; EC 2.7.1.26) is an essential enzyme that catalyzes the phosphorylation of riboflavin (vitamin B2) to form flavin mononucleotide (FMN), an obligatory step in vitamin B2 utilization and flavin cofactor synthesis (Karthikeyan et al., 2003 [PubMed 12623014]).[supplied by OMIM, Nov 2009]
Expression: Ubiquitous expression in colon (RPKM 20.2), duodenum (RPKM 17.4) and 25 other tissues See more

What's a GeneRIF?

Results from a study on gene expression variability markers in early-stage human embryos shows that RFK is a putative expression variability marker for the 3-day, 8-cell embryo stage.
Title: Variability of Gene Expression Identifies Transcriptional Regulators of Early Human Embryonic Development.
DR4 and DR5 have a capability to activate Nox1 by recruiting RFK, resulting in ROS-mediated apoptotic cell death in tumor cells.
Title: Death receptors 4 and 5 activate Nox1 NADPH oxidase through riboflavin kinase to induce reactive oxygen species-mediated apoptotic cell death.
levels of riboflavin kinase expression correlate well with Gleason score, known as a good indicator of patient prognosis
Title: Involvement of riboflavin kinase expression in cellular sensitivity against cisplatin.
Observational study of gene-disease association. (HuGE Navigator)
Title: Genetic variants in nuclear-encoded mitochondrial genes influence AIDS progression.
results suggest that TNF, through the activation of RFK, enhances the incorporation of FAD in NADPH oxidase enzymes, a critical step for the assembly and activation of NADPH oxidase
Title: Riboflavin kinase couples TNF receptor 1 to NADPH oxidase.
the structure of riboflavin kinase cocrystallized with both MgADP and FMN is reported; drastic conformational changes associated with flavin binding are observed primarily at the so-called Flap I and Flap II loop regions

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.
