Structural highlights
Function
IPMK_YEAST Has kinase activity and phosphorylates inositol 1,4,5-trisphosphate (Ins(1,4,5)P3) and inositol 1,3,4,5-tetrakisphosphate (Ins(1,3,4,5)P4). Has low kinase activity towards InsP6. With ARG80, ARG81 and MCM1, coordinates the expression of arginine anabolic and catabolic genes in response to arginine. Recruites ARG80 and MCM21 to stabilize them.[1] [2]
