Enables several functions, including ATP binding activity; magnesium ion binding activity; and mevalonate kinase activity. Involved in isopentenyl diphosphate biosynthetic process, mevalonate pathway and negative regulation of translation. Located in cytosol and peroxisome. Human ortholog(s) of this gene implicated in lipid metabolism disorder; mevalonic aciduria; and porokeratosis. Orthologous to human MVK (mevalonate kinase).
