Human Gene CDK13 (ENST00000340829.10) from GENCODE V44
Description: Homo sapiens cyclin dependent kinase 13 (CDK13), transcript variant 2, mRNA. (from RefSeq NM_031267) RefSeq Summary (NM_003718): 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]. Gencode Transcript: ENST00000340829.10 Gencode Gene: ENSG00000065883.18 Transcript (Including UTRs) Position: hg38 chr7:39,950,121-40,095,555 Size: 145,435 Total Exon Count: 14 Strand: + Coding Region Position: hg38 chr7:39,950,642-40,094,980 Size: 144,339 Coding Exon Count: 14
ID:CDK13_HUMAN DESCRIPTION: RecName: Full=Cyclin-dependent kinase 13; EC=2.7.11.22; EC=2.7.11.23; AltName: Full=CDC2-related protein kinase 5; AltName: Full=Cell division cycle 2-like protein kinase 5; AltName: Full=Cell division protein kinase 13; Short=hCDK13; AltName: Full=Cholinesterase-related cell division controller; FUNCTION: 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. CATALYTIC ACTIVITY: ATP + [DNA-directed RNA polymerase] = ADP + [DNA-directed RNA polymerase] phosphate. CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. SUBUNIT: Interacts with CCNL1 and CCNL2 (By similarity). Interacts with C1QBP. Interacts with HIV-1 Tat. SUBCELLULAR LOCATION: Nucleus speckle. TISSUE SPECIFICITY: Expressed in fetal brain, liver, muscle and in adult brain. Also expressed in neuroblastoma and glioblastoma tumors. PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. RNA EDITING: Modified_positions=103; Note=Edited at about 88%. SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily. SIMILARITY: Contains 1 protein kinase domain. SEQUENCE CAUTION: Sequence=AAA58424.1; Type=Frameshift; Positions=1006; Sequence=AAS07490.1; Type=Erroneous gene model prediction; WEB RESOURCE: Name=NIEHS-SNPs; URL="http://egp.gs.washington.edu/data/cdc2l5/";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
