What pLDDT means and how to read it

Function

Serine/threonine kinase involved in cell cycle control and in RNA polymerase II-mediated RNA transcription (PubMed:9852112, PubMed:19136461, PubMed:26257281, PubMed:28768201). As a cyclin-dependent kinase, CDK7 is activated by the binding to cyclin-H/CCNH and the CDK-activating kinase assembly factor MAT1 (PubMed:41100585). Catalytic subunit of the CDK-activating kinase (CAK) complex, a master regulator of CDK activity by catalyzing the activating threonine phosphorylation of CDKs (PubMed:41100585). CAK activates major mediators of cell cycle control, including CDK1, CDK2, CDK4 and CDK6, and plays a key role in regulating cell cycle progression (PubMed:41100585). CAK complexed to the…

Subunit structure

Component of the CDK-activating kinase (CAK) complex, consisting of CDK7, cyclin-H/CCNH and MAT1, which is a master regulator of CDK activity (PubMed:41100585). CAK binds to both free CDK2 and cyclin-bound CDK2, with a higher affinity for the cyclin-bound form (PubMed:41100585). CAK can further associate with the core-TFIIH to form the TFIIH basal transcription factor (PubMed:9852112). The CAK…
