ITPK4_ARATH | function | Kinase that can phosphorylate the inositol polyphosphate Ins(1,3,4)P3 to form InsP4. Also phosphorylates a racemic mixture of Ins(1,4,6)P3 and Ins(3,4,6)P3 to form InsP4. Does not display inositol 3,4,5,6-tetrakisphosphate 1-kinase activity, but possesses inositol 1,4,5,6-tetrakisphosphate and inositol 1,3,4,5-tetrakisphosphate isomerase activity (PubMed:17698066). Ins(1,3,4,6)P4 is an essential molecule in the hexakisphosphate (InsP6) pathway (By similarity). |
ITPK4_ARATH | similarity | Belongs to the ITPK1 family. |
ITPK4_ARATH | tissue specificity | Expressed in roots, leaf vasculature, cauline leaves, flower buds and siliques. |
