Purification The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name CRIK (CIT Antibody Abstract)
Background Citron was identified by its interactions with activated Rho and Rac. It contains a zinc finger (ZF) region, a pleckstrin homology (PH) domain, a citron/MRCK/Gek (CMG) domain, and a coiled-coil domain with a Rho-Rac binding region (RRB). Citron binds to PSD-95 via its C-terminal tSXV motif and the PDZ domain on PSD-95. This association occurs at post synaptic densities where citron-PSD-95 may provide a specific link between the Rho signaling cascade and the synaptic NMDA receptor complex. Citron Rho-interacting kinase (CRIK) and CRIK short kinase (CRIK-SK) are Ser/Thr kinase isoforms of the myotonic dystrophy kinase family. CRIK contains full-length citron, with an N-terminal kinase domain. CRIK-SK is a splice variant that contains only the kinase domain. CRIK co-localizes with actin in keratinocytes and co-expression of CRIK and Rho increases CRIK kinase activity two-fold. In addition, CRIK mutants cause abnormal contraction during cytokinesis. CRIK is expressed highest in testis, but is also present in brain, spleen, lung, and kidney. Thus, CRIK is a Ser/Thr kinase that functions downstream of Rho during events such as cytokinesis and synaptic transmission.
