Protein attributes
| Sequence length | 315 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. ATP + [DNA-directed RNA polymerase] = ADP + [DNA-directed RNA polymerase] phosphate. |
| Tissue specificity | Expressed in flowers. Ref.6 |
| Sequence similarities | Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily. Contains 1 protein kinase domain. |
| Sequence caution | The sequence AAM61014.1 differs from that shown. Reason: Erroneous initiation. |
