CDK12 Inhibitor: Understanding

CDK12 Inhibitor: Overview

Cyclin-dependent kinase 12 (CDK12) is one of the 20 members of cyclin-dependent kinases (CDK). Each of CDKs binds with cyclin play important roles in the control of cell cycle and cell division and regulates transcription in response to various cellular processes. As a transcription associated CDK, CDK12 binds with cyclin K phosphorylate RNA Pol II at CTD promoting transcription elongation. CDK12 can also interact with RNA processing factors to regulate RNA splicing. Furthermore, CDK12 mediated phosphorylation of RNA Pol II couples mRNA 3' end processing to participate in transcription termination. Besides, CDK12 plays critical role in regulating intronic polyadenylation, epigenetics, as well as translation. CDK12 alterations were found in different human cancers.

CDK12 is mainly composed of three domains: a central Cdc2-related protein kinase domain (KD), an N-terminal "arm", about 700 amino acids, and a C-terminal "arm", about 500 amino acids. The central KD is composed of 300 amino acids and is located at the center of CDK12. Its main function is to mediate the phosphorylation of the C-terminal domain (CTD) of RNAP II. There are 21 RS motifs in the first 400 amino acids of CDK12, and only one RS motif in the rest of the approximately 1000 amino acids. The RS domain, which is enriched arginine and serine, is considered as a prominent feature of CDK12. It was originally found in pre-messenger RNA (pre-mRNA) splicing factors that were important for spliceosome assembly and alternative splice-site selection.

In CDK12, the RS domain mainly functions to target CDK12 to the nuclear speckles. The central KD and the RS domain endow CDK12 the capacity to directly link transcription with the splicing machinery. Proline-rich motifs (PRM) are located between the RS domain and the central KD and are also found in the C-terminal region. The PRM contains the consensus binding sites for Src homology 3 (SH3) and tryptophan (WW) regions which can mediate protein-protein interactions by binding proline-rich modules in ligands. The presence of the RS domain and PRM domain indicates that CDK12 is likely to take part in numerous protein-protein interactions. Notably, the closest human homologue of CDK12 is CDK13. While their sequences of KD are highly homologous, their C- and N-terminal regions differ between CDK12 and CDK13.

CDK12 plays an important role in promoting cancer cell growth, especially in cancers driven by dysregulated transcription factors, such as cancers dependent on MYC (neuroblastoma) and the EWS-FLI1 fusion oncoprotein (Ewing sarcoma). Neuroblastoma is a cancer highly dependent on transcriptional programs. MYC is a proto-oncogene and a major driver of many human cancers. Amplification of n-MYC (MYCN) leads to neuroblastoma. Studies have indicated that THZ1, a CDK12 inhibitor, inhibits MYC expression and tumor growth. In addition, CDK12 plays an important role in the processing of MYC precursor mRNA. Ewing sarcoma is characterized by chromosome rearrangement which fuses the strong transactivation domain of EWS protein with the DNA binding domain of FLI1 protein. EWS/FLI acts as both a transcriptional activator and a transcriptional repressor. Currently, treatment of Ewing sarcoma mainly uses CDK12 inhibitors THZ1 and THZ531, which impair DNA damage repair in an EWS/FLI-dependent manner. The combination of CDK12 and PARP inhibitors is highly active in Ewing Sarcoma. Taken together, targeting CDK12 may be a viable treatment strategy for cancers driven by dysregulated transcription factors.

It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

CDK12 Inhibitor Emerging Drugs

• CT7439: Carrick Therapeutics

CT7439 is an inhibitor of CDK12/13 as well as a 'glue degrader' of Cyclin-K, which is the obligate co-factor for CDK12/13, giving both first-in-class and best-in-class potential. This dual modality significantly increases the potency of the compound and leads to the inhibition of DNA repair at the transcriptional level. CDK12/13 regulates gene transcription through the activation of RNA Polymerase II. It has the potential to synergise with other agents targeting DDR such as the PARP inhibitors in multiple cancer types including breast, ovarian and Ewing's Sarcoma. Currently, the drug is in the Phase I/II stage of its development for the treatment of solid tumors.
