Cdk9 Antibody (YA4790)

Cdk9 Antibody (YA4790) is a mouse-derived and non-conjugated monoclonal antibody, targeting to Cdk9. It can be applicated for WB, IHC-P, ICC/IF, ELISA assays, in the background of human.

The CDK9ic protein emerges as a central player in the intricate regulation of transcription, orchestrating a diverse range of cellular processes. As a pivotal member of the cyclin-dependent kinase pair (CDK9/cyclin-T) complex, also known as positive transcription elongation factor b (P-TEFb), it facilitates the transition from abortive to productive elongation by phosphorylating the C-terminal domain (CTD) of the large subunit of RNA polymerase II (POLR2A), SUPT5H, and RDBP. This complex, inactive in the 7SK small nuclear ribonucleoprotein (snRNP) complex form, engages in phosphorylation events targeting EP300, MYOD1, RPB1/POLR2A, AR, and the negative elongation factors DSIF and NELFE. Beyond its role in transcription, CDK9-CCNK regulates cytokine-inducible transcription networks, promoting RNA synthesis in genetic programs for cell growth, differentiation, and viral pathogenesis. The complex also plays a critical role in cotranscriptional histone modification, mRNA processing, mRNA export, and a network of chromatin modifications. Moreover, it contributes to genome integrity maintenance, replication stress response, and cardiac myocyte enlargement. The multifaceted activities of CDK9-CCNK underscore its significance in governing diverse cellular functions and molecular pathways.
