[[http://www.uniprot.org/uniprot/CDK12_HUMAN CDK12_HUMAN]] Chromosomal aberrations involving CDK12 may be a cause gastric cancer. Deletions within 17q12 region producing fusion transcripts with ERBB2, leading to CDK12-ERBB2 fusion leading to trunctated CDK12 protein not in-frame with ERBB2.

[[http://www.uniprot.org/uniprot/CDK12_HUMAN CDK12_HUMAN]] Cyclin-dependent kinase which displays CTD kinase activity and is required for RNA splicing. Has CTD kinase activity by hyperphosphorylating the C-terminal heptapeptide repeat domain (CTD) of the largest RNA polymerase II subunit RPB1, thereby acting as a key regulator of transcription elongation. Required for RNA splicing, possibly by phosphorylating SRSF1/SF2. Involved in regulation of MAP kinase activity, possibly leading to affect the response to estrogn inhibitors.<ref>PMID:11683387</ref> <ref>PMID:19651820</ref> <ref>PMID:20952539</ref> [[http://www.uniprot.org/uniprot/CCNK_HUMAN CCNK_HUMAN]] May play a role in transcriptional regulation. In vitro, is associated with a kinase activity toward both RNA polymerase II C-terminal domain and CDK2 (CAK).<ref>PMID:10574912</ref>
