N-terminal His6-tagged recombinant human ROCK-II residues 11-552
Product Source: expressed by baculovirus in Sf21 insect cells

Rho kinase (ROCK) is a type of serine/threonine kinase. There are two isoforms, ROCK1 and ROCK2. In humans ROCK1 and ROCK2 are composed of 33 exons and located on chromosome 18 (18q11.1). The ROCK protein structure is characterized by a catalytic kinase domain and Rho-binding domain (RBD) at N-terminal and pleckstrin-homology (PH) domain and an internal cysteine-rich (CR) domain at C-terminal.

Biochem/physiol Actions

Protein Target: ROKα/ROCK-II
Target Sub-Family: AGC

ROCK (Rho kinase) is activated by interacting with Rho GTPase enzyme. ROCK plays a crucial role in various essential cellular functions like adhesion, contraction, migration, and proliferation. Moreover, it regulates the cytoskeleton and actomyosin contractility during apoptosis. Overexpression of ROCK protein has been observed in various types of cancer such as osteosarcoma, hepatocellular carcinomas, colon and bladder cancers.

The Ras-related GTPase RhoA controls signalling processes required for cytoskeletal reorganisation, transcriptional regulation, and transformation. The ability of RhoA mutants to transform cells correlates not with transcription but with their ability to bind ROCK-I, an effector kinase involved in cytoskeletal
