General annotation (Comments)
| Function | 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. Required for centrosome positioning and centrosome-dependent exit from mitosis. Plays a role in terminal erythroid differentiation. Promotes keratinocyte terminal differentiation By similarity. 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. May regulate closure of the eyelids and ventral body wall by inducing the assembly of actomyosin bundles. Ref.4 Ref.5 Ref.6 Ref.7 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Cofactor | Magnesium By similarity. |
| Enzyme regulation | Activated by RHOA binding. Inhibited by Y-27632 By similarity. |
| Subunit structure | Homodimer By similarity. Interacts with RHOA (activated by GTP), RHOB, RHOC, GEM, MYLC2B, RHOE, PPP1R12A, LIMK1, LIMK2, TSG101, CHORDC1, DAPK3, PFN1 and JIP3 By similarity. Interacts with FHOD1 in a Src-dependent manner By similarity. Interacts with PTEN. Ref.7 |
| Subcellular location | Cytoplasm. Cytoplasm › cytoskeleton › centrosome › centriole. Golgi apparatus membrane; Peripheral membrane protein By similarity. Cell projection › bleb By similarity. Note: Associated with the mother centriole and an intercentriolar linker. A small proportion is associated with Golgi membranes By similarity. |
| Tissue specificity | Highly expressed in brain, heart, lung, liver, stomach, spleen, kidney, testis, muscle, embryo and placenta. Ref.1 |
| Domain | The C-terminal auto-inhibitory domain interferes with kinase activity. RHOA binding leads to a conformation change and activation of the kinase. Truncated ROCK1 is constitutively activated. |
| Post-translational modification | Autophosphorylated on serine and threonine residues. Cleaved by caspase-3 during apoptosis. This leads to constitutive activation of the kinase and membrane blebbing By similarity. |
| Disruption phenotype | Mice exhibit both EOB (eyes open at birth) and omphalocele phenotypes as a result of disorganization of actomyosin cables in the eyelid epithelium and defective actin assembly in the umbilical ring. Ref.4 |
| Sequence similarities | Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. Contains 1 AGC-kinase C-terminal domain. Contains 1 PH domain. Contains 1 phorbol-ester/DAG-type zinc finger. Contains 1 protein kinase domain. Contains 1 REM (Hr1) repeat. |
| Sequence caution | The sequence AAH57154.1 differs from that shown. Reason: Contaminating sequence. Potential poly-A sequence. The sequence BAC34154.1 differs from that shown. Reason: Erroneous initiation. |
Ontologies
Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: P70335-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: P70335-2) The sequence of this isoform differs from the canonical sequence as follows: 425-425: Missing. | ||||||
| Note: May be due to a competing donor splice site. No experimental confirmation available. |
