Protein kinase which is a key regulator of actin cytoskeleton and cell polarity. Involved in regulation of smooth muscle contraction, actin cytoskeleton organization, stress fiber and focal adhesion formation, neurite retraction, cell adhesion and motility via phosphorylation of DAPK3, GFAP, LIMK1, LIMK2, MYL9/MLC2, PFN1 and PPP1R12A. Phosphorylates FHOD1 and acts synergistically with it to promote SRC-dependent non-apoptotic plasma membrane blebbing. Phosphorylates JIP3 and regulates the recruitment of JNK to JIP3 upon UVB-induced stress. Acts as a suppressor of inflammatory cell migration by regulating PTEN phosphorylation and stability. Acts as a negative regulator of VEGF-induced angiogenic endothelial cell activation. Required for centrosome positioning and centrosome-dependent exit from mitosis. Plays a role in terminal erythroid differentiation. May regulate closure of the eyelids and ventral body wall by inducing the assembly of actomyosin bundles. Promotes keratinocyte terminal differentiation. Homodimer. Interacts with RHOB, RHOC, MYLC2B snd PTEN. Interacts with RHOA (activated by GTP), CHORDC1, DAPK3, GEM, JIP3, RHOE, PPP1R12A, PFN1, LIMK1, LIMK2 and TSG101. Interacts with FHOD1 in a Src-dependent manner. Detected in blood platelets. Activated by RHOA binding. Inhibited by Y- 27632. Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. Note: This description may include information from UniProtKB.
