Plays a role in cytokinesis (By similarity). Required for KIF14 localization to the central spindle and midbody (By similarity). Putative RHO/RAC effector that binds to the GTP-bound forms of RHO and RAC1 (By similarity). It probably binds p21 with a tighter specificity in vivo (By similarity). Displays serine/threonine protein kinase activity (By similarity). Plays an important role in the regulation of cytokinesis and the development of the central nervous system (PubMed:24695496). Phosphorylates MYL9/MLC2 (By similarity). ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-[protein] ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-threonyl-[protein] Homodimer (By similarity). Directly interacts with KIF14 depending on the activation state (stronger interaction with the kinase-dead form) (By similarity). Interacts with TTC3 (By similarity). Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family.
