Description

General description

Cyclin-dependent kinase 13 (UniProt: Q14004: also known as Cdk13, EC:2.7.11.22, EC:2.7.11.23, CDC2-related protein kinase 5, Cell division cycle 2-like protein kinase 5, Cell division protein kinase 13, hCDK13, Cholinesterase-related cell division controller) is encoded by the CDK13 (also known as CDC2L, CDC2L5, CHED, KIAA1791) gene (Gene ID:8621) in human. CDK13 is a member of the cyclin-dependent serine/threonine protein kinase family. Members of this family are known to play a vital role as master switches in cell cycle control. Human CDK 13 shares 43% sequence identity with CDK12. CDK13 is expressed in fetal brain, liver, muscle, in adult brain and in neuroblastoma and glioblastoma tumors. It contains expanded regions of serine-arginine (SR) motifs in its N-terminal regions, which links it to the SR protein family involved in RNA processing and pre-mRNA splicing. CDK13 contains a C-terminal extension helix that is composed of a polybasic cluster and a DCHEL motif that interacts with the bound ATP. CDK13 displays C-terminal repeat domain (CTD) kinase activity and is required for RNA splicing. It hyperphosphorylates the C-terminal heptapeptide repeat domain of the largest RNA polymerase II subunit RPB1 and acts a key regulator of transcription elongation. Phosphorylation of the three serine residues (Ser 2, 5, and 7) within the CTD is linked to the phases of RNAPII-mediated transcription. Phosphorylation of Ser7 (pSer7) starts the transcription cycle that primes the CTD for further modifications. (Ref.:Greifenberg, AK et al. (2016). Cell Reports 14(2): 320-331).
