Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Cyclin-dependent kinase that phosphorylates the C-terminal domain (CTD) of the large subunit of RNA polymerase II (POLR2A), thereby acting as a key regulator of transcription elongation. Regulates the expression of genes involved in DNA repair and is required for the maintenance of genomic stability. Preferentially phosphorylates 'Ser-5' in CTD repeats that are already phosphorylated at 'Ser-7', but can also phosphorylate 'Ser-2'. Required for RNA splicing, possibly by phosphorylating SRSF1/SF2. Involved in regulation of MAP kinase activity, possibly leading to affect the response to estrogen inhibitors.CATALYTIC ACTIVITY [DNA-directed RNA polymerase] + ATP = phospho-[DNA-directed RNA polymerase] + ADP + H(+)CATALYTIC ACTIVITY L-seryl-[protein] + ATP = O-phospho-L-seryl-[protein] + ADP + H(+)CATALYTIC ACTIVITY L-threonyl-[protein] + ATP = O-phospho-L-threonyl-[protein] + ADP + H(+)ACTIVITY REGULATION Inhibited by the ATP analog flavopiridol, purvalanol A, purvalanol B, staurosporine and CR8.SUBUNIT Interacts with CCNL1 and CCNL2 (By similarity). Interacts with CCNK.SUBUNIT (Microbial infection) Interacts with human herpes virus 1 (HHV-1) transcriptional regulator ICP22.SUBCELLULAR LOCATION Colocalized with nuclear speckles throughout interphase.ALTERNATIVE PRODUCTS Widely expressed.PTM Phosphorylation at Thr-893 increases kinase activity.DISEASE 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.SIMILARITY Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily.SEQUENCE CAUTION Extended N-terminus.
