This gene is a member of the family of dihydroxyacetone kinases, which have a protein structure distinct from other kinases. The product of this gene phosphorylates dihydroxyacetone, and also catalyzes the formation of riboflavin 4',5'-phosphate (aka cyclin FMN) from FAD. Several alternatively spliced transcript variants have been identified, but the full-length nature of only one has been determined. [provided by RefSeq]

dihydroxyacetone kinase 2 homolog (S. cerevisiae)

Catalyzes both the phosphorylation of dihydroxyacetone and of glyceraldehyde, and the splitting of ribonucleoside diphosphate-X compounds among which FAD is the best substrate. Represses IFIH1-mediated cellular antiviral response (PubMed:17600090).

Triokinase and FMN cyclase deficiency syndrome (TKFCD):
An autosomal recessive disease characterized by cataracts and developmental delay that may be associated with cerebellar hypoplasia. Additional features may include liver dysfunction, microcytic anemia, and fatal cardiomyopathy with lactic acidosis following a febrile illness.
