IPK1 Ipk1p

Ipk1, inositol 1,3,4,5,6-pentakisphosphate 2-kinase, Ins(1,3,4,5,6)P5 2-kinase
The protein encoded by this gene is a kinase that phosphorylates position 2 of inositol-1,3,4,5,6-pentakisphosphate to form inositol-1,2,3,4,5,6-hexakisphosphate (InsP6). InsP6 has a variety of functions, including stimulation of DNA repair, endocytosis, and mRNA export. [provided by RefSeq, Nov 2010] (from NCBI)
