The human cyclin-dependent kinase inhibitor 2A (CDKN2A) gene generates several transcript variants that differ in their first exons. At least three alternatively spliced variants encoding distinct proteins have been reported. One of these, cyclin-dependent kinase inhibitor 2A (melanoma, p16, inhibits CDK4) or p16INK4a, interacts with, and sequesters, the E3 ubiquitin-protein ligase MDM2, a protein responsible for the degradation of p53. Thus, p16-INK4a functions as a tumor suppressor in a variety of cells. Mutations in the CDKN2A gene are often found in many tumors. p16INK4a is also suggested to play a role in controlling cell proliferation and apoptosis during mammary gland development. p16-INK4a is also known as cyclin-dependent kinase 4 inhibitor A, CDK4 inhibitor p16-INK4, cell cycle negative regulator beta, multiple tumor suppressor 1 (MTS-1), ARF, MLM, p14, p16, p19, CMM2, INK4, INK4A, TP16, CDK4I, CDKN2, p14-ARF, p19-ARF, and p16-INK4.. ...
CDKs (Cyclin-dependent kinases) are serine-threonine kinases first discovered for their role in regulating the cell cycle. They are also involved in regulating transcription, mRNA processing, and the differentiation of nerve cells. CDKs are relatively small proteins, with molecular weights ranging from 34 to 40 kDa, and contain little more than the kinase domain. In fact, yeast cells can proliferate normally when their CDK gene has been replaced with the homologous human gene. By definition, a CDK binds a regulatory protein called a cyclin. Without cyclin, CDK has little kinase activity; only the cyclin-CDK complex is an active kinase.. There are around 20 Cyclin-dependent kinases (CDK1-20) known till date. CDK1, 4 and 5 are involved in cell cycle, and CDK 7, 8, 9 and 11 are associated with transcription.. CDK levels remain relatively constant throughout the cell cycle and most regulation is post-translational. Most knowledge of CDK structure and function is based on CDKs of S. pombe (Cdc2), S. ...
... cellular proliferation via inhibition of CDK activities. routine and g27Kip1 (hereafter g27) can regulate CDK actions.1-3 The p27 protein was originally known as an inhibitor of CDK activities for things containing CDK2 and shown to inhibit cyclin E and cyclin A activities which regulate G1 and S phase traverse.4-6 In addition to CDK inhibition, g27 provides other multifarious connections with cyclin N/cdk4 processes putatively.7 Since cellular amounts of g27 are elevated in response to high cell thickness, serum deprival, and TGF, it was hypothesized g27 brought cells into quiescence and held them in G0 through the inhibition of CDK actions.8 Numerous reviews have got characterized the control of p27 including the control of its transcription,9,10 translation,11,12 post-translational adjustments.7,13,14 cellular localization15-19 and balance.20-23 The regulations of its stability has a main role in adjusting mobile ...
Activation of the cyclin-dependent kinases to promote cell cycle progression requires their association with cyclins as well as phosphorylation of a threonine (residue 161 in human p34cdc2). This phosphorylation is carried out by CAK, the Cdk-activating kinase. We have purified and cloned CAK from S …
Progestin antagonists inhibit the proliferation of progesterone receptor-positive cells, including breast cancer cells, by G1 phase-specific actions, but the molecular targets involved are not defined. Reduced phosphorylation of pRB, a substrate for G1 cyclin-dependent kinases (CDKs) in vivo, was apparent after 9 h treatment of T-47D breast cancer cells with the antiprogestins RU 486 or ORG 31710, accompanying changes in S phase fraction. Although the abundance of cyclin D1, Cdk4, and Cdk6 did not decrease cyclin D1-associated kinase activity was reduced by approximately 50% at 9-18 h. Similarly, cyclin E-associated kinase activity decreased by approximately 60% at 12-24 h in the absence of significant changes in the abundance of cyclin E and Cdk2. The CDK inhibitor p21 increased in mRNA and protein abundance and was present at increased levels in cyclin D1 and cyclin E complexes at times when their kinase activity was decreased. Increased p21 protein abundance was observed in another antiprogestin

N2 - Inducible transcriptional elongation is a rapid, stereotypic mechanism for activating immediate early immune defense genes by the epithelium in response to viral pathogens. Here, the recruitment of a multifunctional complex containing the cyclin dependent kinase 9 (CDK9) triggers the process of transcriptional elongation activating resting RNA polymerase engaged with innate immune response (IIR) genes. To identify additional functional activity of the CDK9 complex, we conducted immunoprecipitation (IP) enrichment-stable isotope labeling LC-MS/MS of the CDK9 ...
A8326 AZD-5438 AZD5438 is a potent small molecule inhibitor of cyclin-dependent kinase (CDK) 1, 2 and 9 with half maximal inhibitory concentration IC50 of 16 nmol/L, 6 nmol/L and 20 nmol/L respectively. AZD5438 has also been found to potently inhibit the human cyclin E/CDK2 complex, the cyclin B1/CDK1 complex and the cyclin A/CDK2 complex with IC50 of 0.006 μM, 0.016 μM and 0.045 μM respectively. In previous studies, AZD5438 has exhibited significant anti-proliferative activity in a few human tumor cell lines with IC50 ranging from 0.2 μmol/L to 1.7 μmol/L, in which the phosphorylation of a few proteins, including CDK substrates pRb, nucleolin, protein phosphatase 1a and RNA polymerase II COOH-terminal domain, and cell cycling at G2-M, S and G1 phases were inhibited. ...

Antigen Background p27 protein, also known as kinase inhibitory protein 1 (Kip1), binds to cyclin E/cdk2 complexes, but not to cdk2 alone, and is detected in purified extracts of growth-arrested cells. p27 protein constrains cell proliferation by setting the threshold level of cyclin E necessary to activate cdk2. The p27 protein is also present in proliferating cells, but only in a sequestered form when it is unavailable to interact with cyclin E/cdk2 complexes. It is likely that cyclin D complexed with catalytically inactive cdk4 is sufficient to sequester p27 protein and titrate its function. The presence of bound p27 protein in proliferating cells suggests that its role may not be restricted to inducing cell cycle arrest but to also set the cyclin E threshold for execution of the G1 to S phase transition during each mitotic cycle.. ...
If you have a question about this talk, please contact Caroline Newnham.. Host: Viji Draviam. Tissue homeostasis in metazoans is regulated by transitions of cells between quiescence and proliferation. The hallmark of proliferating populations is progression through the cell cycle, which is driven by Cyclin-dependent kinase (CDK) activity. I will discuss our recent development of a live-cell sensor for CDK2 activity and the finding that proliferating cells bifurcate into two populations as they exit mitosis. Some cells immediately commit to the next cell cycle by building up CDK2 activity from an intermediate level, while other cells lack CDK2 activity and enter a transient state of quiescence. This bifurcation is directly controlled by the CDK inhibitor p21 and is regulated by mitogens during a restriction window at the end of the previous cell cycle. We are currently exploring the role of cell stress in controlling this bifurcation in an attempt to uncover the root cause of this striking ...
Dinaciclib, also known as SCH727965, is a potent CDK inhibitor with potential antineoplastic activity. Dinaciclib selectively inhibits cyclin dependent kinases CDK1, CDK2, CDK5, and CDK9 activity in vitro with IC(50) values of 1, 1, 3, and 4 nmol/L, respectively. Compared with flavopiridol, Dinaciclib exhibits superior activity with an improved therapeutic index. Dinaciclib induced regression of established solid tumors in a range of mouse models following intermittent scheduling of doses below the maximally tolerated level..
