Enables riboflavin kinase activity. Involved in FMN biosynthetic process. Located in mitochondrial inner membrane. Used to study cancer. Orthologous to human RFK (riboflavin kinase).
SGD Description
Riboflavin kinase, produces riboflavin monophosphate (FMN); FMN is a necessary cofactor for many enzymes; predominantly localizes to the microsomal fraction and also found in the mitochondrial inner membrane; human RFK functionally complements the lethality of the null mutation
