Previous Symbols for CDK13 Gene
The protein encoded by this gene is a member of the cyclin-dependent serine/threonine protein kinase family. Members of this family are well known for their essential roles as master switches in cell cycle control. The exact function of this protein has not yet been determined, but it may play a role in mRNA processing and may be involved in regulation of hematopoiesis. Alternatively spliced transcript variants have been described.[provided by RefSeq, Dec 2009]
GeneCards Summary for CDK13 Gene
CDK13 (Cyclin-Dependent Kinase 13) is a Protein Coding gene. GO annotations related to this gene include protein kinase activity and RNA polymerase II carboxy-terminal domain kinase activity. An important paralog of this gene is CDK12.
UniProtKB/Swiss-Prot for CDK13 Gene
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, probably by phosphorylating SRSF1/SF2. Required during hematopoiesis. In case of infection by HIV-1 virus, interacts with HIV-1 Tat protein acetylated at Lys-50 and Lys-51, thereby increasing HIV-1 mRNA splicing and promoting the production of the doubly spliced HIV-1 protein Nef.
