StrainBaker's yeast
Description1D-Myo-Inositol 1,4,5,6-tetrakisphosphate (IP4) is an intermediate in inositol pyrophosphates biosynthesis pathway. IP4 is the precursor to IP5 in 1D-myo-inositol hexakisphosphate (IP6) biosynthesis pathway. IP6 is one of the most prevalent forms of phosphorylated inositols in the eukaryotic cell. It is a strong chelator of important minerals such as calcium, magnesium, iron and zinc. The main function of IP6 in yeast is related to regulation of mRNA export from the nucleus.

Enzymes

General function:
Involved in inositol trisphosphate 3-kinase activity
Specific 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. Originally it was proposed that the ARGRI and ARGRIII proteins are more likely to be involved in the control of ARGRII activity
