WebAug 12, 2005 · Finally, p21 was phosphorylated by Cdk2 at Ser-130 in vitro, and this ability of Cdk2 to phosphorylate p21 was dependent, in large part, on the presence of cy2. These results support a model in which active Cdk2 destabilizes p21 via the cy2 cyclin-binding motif and p21 phosphorylation. WebJul 12, 2024 · During the G1-S transition, the activity of Cdk2 is regulated by its association with p27KIP1, which in rodent fibroblasts undergoes phosphorylation mainly at serine 10, threonine 187, and C ...

WebOct 13, 2008 · Characterization of the engineered CDKs. (a) Cyclin E-CDK2/3 complexes, or their F80A engineered counterparts (indicated by asterisks), were immunoprecipitated from transfected U2OS cell lysates via the HA-tag on the CDK subunit and subjected to in vitro kinases assays with 10 μM of either normal ATP or PE-ATP analogue. Phosphorylation … WebNov 9, 2012 · Our data indicate that CDK2 phosphorylates CDK9 on Ser 90 and thereby contributes to HIV-1 transcription. The phosphorylation of Ser90 by CDK2 represents a novel mechanism of HIV-1 regulated transcription and provides a new strategy for activation of latent HIV-1 provirus. gold star foods ontario california
