Expressed in the brain (at protein level).

The protein encoded by this gene is a serine/threonine kinase that regulates cytokinesis, smooth muscle contraction, the formation of actin stress fibers and focal adhesions, and the activation of the c-fos serum response element. This protein, which is an isozyme of ROCK1 is a target for the small GTPase Rho. [provided by RefSeq]



Score>80(red) has high confidence and is suggested to be used for WB detection. *The prediction model is mainly based on the alignment of immunogen sequences, the results are for reference only, not as the basis of quality assurance.

Research Backgrounds


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 an important role in generating the circadian rhythm of the aortic myofilament Ca(2+) sensitivity and vascular contractility by modulating the myosin light chain phosphorylation.


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.

Tissue Specificity:

Expressed in the brain (at protein level).

Subunit Structure:

Homodimer (By similarity). Interacts with IRS1 (By similarity). Interacts with RAF1 (By similarity). Interacts with RHOA (activated by GTP), RHOB and RHOC (By similarity). Interacts with PPP1R12A. Interacts with EP300. Interacts with CHORDC1. Interacts with BRCA2. Interacts with NPM1; this interaction enhances ROCK2 activity. Interacts with SORL1.


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

Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family.
