Protein attributes
| Sequence length | 815 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Plays a role in sugar-mediated root development. Interaction with CINV1 induces repression of CINV1 activity and negative regulation of sugar-mediated root cell elongation. Ref.7 |
| Catalytic activity | ATP + 1-phosphatidyl-1D-myo-inositol 4-phosphate = ADP + 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate. |
| Subunit structure | Interacts with CINV1. Ref.7 |
| Subcellular location | Membrane; Peripheral membrane protein Probable. Nucleus. |
| Tissue specificity | Widely expressed. Ref.7 |
| Induction | Transiently down-regulated by cold. Ref.7 |
| Miscellaneous | The gain-of-function mutant pip5k9-d (T-DNA insertion line) has reduced primary root length (Ref.7). |
| Sequence similarities | Contains 8 MORN repeats. Contains 1 PIPK domain. |
