Cdk7 phosphorylation

WebWhen active in CTD phosphorylation, CDK7 is found as part of a CDK7/cyclinH/MAT 1 (menage à trois) complex which associates with core subunits of the transcription factor TFIIH to form holo-TFIIH. MAT1 plays multiple roles in this context: firstly by promoting the association of CDK7 with cyclin H which would otherwise require CDK7 ... WebMay 31, 2024 · CDK7 targeted phosphorylation of these receptors is required for full activity and directed ubiquitination and proteasomal degradation critical for the cyclical recruitment of these transcription factors to gene promoters (15, 16, 20, 21).

The transcription factor TFIIH is a kinase and will hyperphosphorylate the CTD of RNAP, and in doing so, causes the RNAP complex to move away from the initiation site. WebNov 13, 2013 · Previously, we have shown that CDK7 and SRC1 bind preferentially to the SUMOylation-deficient form of NR5A1 and that CDK inhibition reduces NR5A1 phosphorylation , suggesting that SUMOylation inhibits NR5A1 activity by reducing CDK7-mediated phosphorylation of NR5A1.
