Comment typeDescription
Catalytic ActivityATP + 1-phosphatidyl-1D-myo-inositol 4- phosphate = ADP + 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate.
FunctionPlays a role in sugar-mediated root development. Interaction with CINV1 induces repression of CINV1 activity and negative regulation of sugar-mediated root cell elongation. {ECO:0000269|PubMed:17220200}.
InductionTransiently down-regulated by cold. {ECO:0000269|PubMed:17220200}.
InteractionQ9LQF2:CINV1; NbExp=6; IntAct=EBI-2008013, EBI-2008033;
MiscellaneousThe gain-of-function mutant pip5k9-d (T-DNA insertion line) has reduced primary root length. {ECO:0000305|PubMed:17220200}.
SimilarityContains 1 PIPK domain. {ECO:0000255|PROSITE- ProRule:PRU00781}.
SimilarityContains 8 MORN repeats. {ECO:0000305}.
Subcellular LocationMembrane {ECO:0000305}; Peripheral membrane protein {ECO:0000305}. Nucleus.
SubunitInteracts with CINV1. {ECO:0000269|PubMed:17220200}.
Tissue SpecificityWidely expressed. {ECO:0000269|PubMed:17220200}.
