Function

This gene is a member of the prenyltransferase family and encodes a protein with geranylgeranyl diphosphate (GGPP) synthase activity. The enzyme catalyzes the synthesis of GGPP from farnesyl diphosphate and isopentenyl diphosphate. GGPP is an important molecule responsible for the C20-prenylation of proteins and for the regulation of a nuclear hormone receptor. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.[7]

Much like its homolog farnesyl diphosphate synthase, GGPS1 is inhibited by bisphosphonate compounds.[8]

Clinical

Mutations in both copies of this gene have been associated with a syndrome of muscular dystrophy, hearing loss and ovarian insufficiency.[9]
