Predicted to enable riboflavin kinase activity. Predicted to be involved in FMN biosynthetic process and riboflavin metabolic process. Predicted to act upstream of or within apoptotic process; positive regulation of NAD(P)H oxidase activity; and reactive oxygen species metabolic process. Predicted to be active in mitochondrion. Orthologous to human RFK (riboflavin kinase). [provided by Alliance of Genome Resources, Apr 2022]
