Previous GeneCards Identifiers for RFK Gene
Riboflavin kinase (RFK; EC 126.96.36.199) 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]
GeneCards Summary for RFK Gene
RFK (Riboflavin Kinase) is a Protein Coding gene. Diseases associated with RFK include Riboflavin Deficiency and Brown-Vialetto-Van Laere Syndrome. Among its related pathways are Folate Metabolism and Metabolism of water-soluble vitamins and cofactors. Gene Ontology (GO) annotations related to this gene include riboflavin kinase activity.
UniProtKB/Swiss-Prot Summary for RFK Gene
Catalyzes the phosphorylation of riboflavin (vitamin B2) to form flavin-mononucleotide (FMN), hence rate-limiting enzyme in the synthesis of FAD. Essential for TNF-induced reactive oxygen species (ROS) production. Through its interaction with both TNFRSF1A and CYBA, physically and functionally couples TNFRSF1A to NADPH oxidase. TNF-activation of RFK may enhance the incorporation of FAD in NADPH oxidase, a critical step for the assembly and activation of NADPH oxidase.
