Activity of the GTP-binding proteins is regulated by GAPs, that accelerate binding, and GTPases, that enhance the rate of GTP hydrolysis (Ras, Rho, cdc42Hs, and Rac). The isoforms of Rho, a small GTP-binding protein, regulate cellular processes such as the formation of the stress fibers, lamelipodia, and filopodia. ROKα (RhoA-binding kinase) is a Ser/Thr protein kinase that interects with the GTP-binding form of RhoA. Like RhoA, ROKα localizes at the cellular margins and colocalizes with acti filaments. The ROKα gene encodes a protein of 1302 amino acids with homology to the human myotonic kinase. Although ROKα binds to GTP-RhoA, it is not yet clear whether this interaction induces the kinase activity of ROKα.

注意事项:
1.Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2.Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
