Introduction to Recombinant Human CDK9 Protein

Recombinant Human CDK9 Protein, also known as Cyclin Dependent Kinase 9, is a highly conserved protein that plays a crucial role in regulating cell cycle progression and gene transcription. It is a member of the CDK family of proteins, which are key regulators of cell division and proliferation. Recombinant Human CDK9 Protein is produced through genetic engineering techniques, making it a valuable tool for studying its structure, activity, and potential applications.

Structure of Recombinant Human CDK9 Protein

Recombinant Human CDK9 Protein is a 42 kDa protein consisting of 372 amino acids. It contains a conserved serine/threonine kinase domain and a cyclin-binding domain, which are essential for its activity. The protein also has a T-loop region, which is important for its regulation and interaction with other proteins. Recombinant Human CDK9 Protein has a high degree of homology with its counterparts in other species, indicating its evolutionary conservation and importance in cellular processes.

Activity of Recombinant Human CDK9 Protein

Recombinant Human CDK9 Protein is a key regulator of the cell cycle, specifically in the G1, S, and G2 phases. It forms a complex with its regulatory partner, Cyclin T, to form the active complex, CDK9/Cyclin T. This complex is responsible for the phosphorylation of the C-terminal domain of RNA polymerase II, which is critical for transcriptional elongation. Additionally, Recombinant Human CDK9 Protein can also phosphorylate other targets, such as transcription factors and RNA splicing factors, to regulate gene expression. Its activity is tightly regulated by other proteins, such as CDK inhibitors and phosphatases, to ensure proper cell cycle progression and transcriptional control.
