ARG82

Gene
ARG82
Protein
Inositol polyphosphate multikinase
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Length
355 amino acids
Function
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. Recruits ARG80 and MCM21 to stabilize them.
Similarity
Belongs to the inositol phosphokinase (IPK) family.
