General Info
Function
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.
Tissue specificity
Ubiquitously expressed.
Involvement in 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.
Sequence similarities
Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX
subfamily.
Contains 1 protein kinase domain.
Post-translational
modifications
Phosphorylation at Thr-893 increases kinase activity.
Cellular localization
Nucleus. Nucleus speckle. Colocalized with nuclear speckles throughout interphase.
