CRK7 is a CDC2/CDK -type protein kinase. Also known as CRKRS, the protein has an arginine/serine-rich (RS) domain that is found predominantly in splicing factors, and extensive proline-rich regions that match the consensus for SH3 and WW domain binding sites. Anti-CrkRS immunoprecipitates have been shown to phosphorylate the C-terminal domain of RNA polymerase II in vitro. CRK7 has been shown to be expressed ubiquitously. Nuclear staining is seen in some carcinomas (breast, lung, others), this may be because these cells are actively dividing and this gene is associated with cell division. ESTs have been isolated from several tissue libraries, including normal lymph and cancerous bone.
