General annotation (Comments)
| Function | 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 By similarity. |
| Catalytic activity | ATP + riboflavin = ADP + FMN. |
| Cofactor | Zinc or magnesium By similarity. |
| Pathway | Cofactor biosynthesis; FMN biosynthesis; FMN from riboflavin (ATP route): step 1/1. |
| Subunit structure | Monomer By similarity. Directly interacts with TNFRSF1A death domain; this interaction may be supported by TRADD. In the absence of TNFRSF1A, interacts with TRADD. Independently of TNFRSF1A, interacts with the NADPH oxidase subunit CYBA. Ref.4 |
| Subcellular location | Cytoplasm By similarity. |
| Disruption phenotype | Mutant embryos die in utero before 7.5 dpc. Ref.4 |
