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. Plays a role in placental homeostasis during the perinatal period. Ref.4 Ref.7 Ref.8 Ref.9

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), CHORDC1, IRS1, RHOB, RHOC, PPP1R12A, SORL1, EP300 and BRCA2 By similarity. Interacts with NPM1 and this interaction enhances its activity By similarity. Interacts with RAF1 By similarity.

Subcellular location

Isoform 1: Cytoplasm. Cell membrane; Peripheral membrane protein Ref.2. Nucleus By similarity. Cytoplasmcytoskeletoncentrosome By similarity. Note: Cytoplasmic, and associated with actin microfilaments and the plasma membrane By similarity. Ref.2

Isoform 2: Cytoplasm. Cell membrane; Peripheral membrane protein Ref.2.

Tissue specificity

Highly expressed in brain, heart, lung, liver, stomach, spleen, kidney, testis, muscle, embryo and placenta. Isoform 2 is expressed predominantly in the skeletal muscle. Ref.1 Ref.2

Domain

An interaction between Thr-414 and Asp-48 is essential for kinase activity and dimerization By similarity.

Post-translational modification

Autophosphorylated. Phosphorylation at Tyr-722 reduces its binding to RHOA and is crucial for focal adhesion dynamics. Dephosphorylation by PTPN11 stimulates its RHOA binding activity By similarity. Ref.2

Cleaved by granzyme B during apoptosis. This leads to constitutive activation of the kinase and membrane blebbing.

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. Mice are impaired in both basal synaptic transmission and hippocampal long-term potentiation (LTP). Embryos manifest extensive thrombus formation in the placenta, resulting in placental dysfunction, intrauterine growth retardation, and fetal death. Ref.4 Ref.5 Ref.8

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.
