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 ADD1, BRCA2, CNN1, EZR, DPYSL2, EP300, MSN, MYL9/MLC2, NPM1, RDX, PPP1R12A and VIM. Phosphorylates SORL1 and IRF4. Acts as a negative regulator of VEGF-induced angiogenic endothelial cell activation. Positively regulates the activation of p42/MAPK1-p44/MAPK3 and of p90RSK/RPS6KA1 during myogenic differentiation. Plays an important role in the timely initiation of centrosome duplication. Inhibits keratinocyte terminal differentiation. May regulate closure of the eyelids and ventral body wall through organization of actomyosin bundles. Plays a critical role in the regulation of spine and synaptic properties in the hippocampus. Ref.4 Ref.5 Ref.6 Ref.7 Ref.11 Ref.12 Ref.18 Ref.19 |
| 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. Interacts with IRS1, RHOB and RHOC By similarity. Interacts with RHOA (activated by GTP), PPP1R12A, CHORDC1, SORL1, EP300 and BRCA2. Interacts with NPM1 and this interaction enhances its activity. Interacts with RAF1 By similarity. Ref.4 Ref.6 Ref.7 Ref.11 Ref.14 Ref.18 Ref.19 |
| Subcellular location | Cytoplasm. Cell membrane; Peripheral membrane protein By similarity. Nucleus. Cytoplasm › cytoskeleton › centrosome. Note: Cytoplasmic, and associated with actin microfilaments and the plasma membrane By similarity. Ref.6 Ref.7 |
| Domain | An interaction between Thr-414 and Asp-48 is essential for kinase activity and dimerization By similarity. |
| Post-translational modification | Phosphorylation at Tyr-722 reduces its binding to RHOA and is crucial for focal adhesion dynamics. Dephosphorylation by PTPN11 stimulates its RHOA binding activity. Cleaved by granzyme B during apoptosis. This leads to constitutive activation of the kinase and membrane blebbing. |
| 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 AAX93049.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence BAA31594.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
