General annotation (Comments)
| Function | Required for KIF14 localization to the central spindle and midbody. May play a role in cytokinesis. Putative RHO/RAC effector that binds to the GTP-bound forms of RHO and RAC1. It probably binds p21 with a tighter specificity in vivo. Dual specificity protein kinase activity catalyzing autophosphorylation and phosphorylation of exogenous substrates on both serine/threonine and tyrosine residues. Plays an important role in the regulation of cytokinesis and the development of the central nervous system By similarity. |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Subunit structure | Directly interacts with KIF14 depending on the activation state (stronger interaction with the kinase-dead form). Homodimer By similarity. |
| Subcellular location | CytoplasmBy similarity. |
| Sequence similarities | Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. Contains 1 AGC-kinase C-terminal domain. Contains 1 CNH domain. Contains 1 PH domain. Contains 1 phorbol-ester/DAG-type zinc finger. Contains 1 protein kinase domain. |
