Regulation of CDK7 substrate specificity by MAT1 and TFIIH.
The cyclin-dependent kinase (CDK)-activating kinase CAK has been proposed to function in the control of cell cycle progression, DNA repair and RNA polymerase II (pol II) transcription. Most CAK exists as complexes of three subunits: CDK7, cyclin H (CycH) and MAT1. This tripartite CAK occurs in a free form and in association with 'core' TFIIH, which functions in both pol II transcription and DNA...
متن کاملRepression of TFIIH transcriptional activity and TFIIH-associated cdk7 kinase activity at mitosis.
Nuclear transcription is repressed when eukaryotic cells enter mitosis. Mitotic repression of transcription of various cellular and viral gene promoters by RNA polymerase II can be reproduced in vitro either with extracts prepared from cells arrested at mitosis with the microtubule polymerization inhibitor nocodazole or with nuclear extracts prepared from asynchronous cells and the mitotic prot...

متن کاملMolecular cloning of CDK7-associated human MAT1, a cyclin-dependent kinase-activating kinase (CAK) assembly factor.
Mammalian CDK7 is a protein kinase identified as the catalytic subunit of cyclin-dependent kinase (CDK)-activating kinase and as an essential component of the transcription factor TFIIH that is involved in transcription initiation and DNA repair. We have identified in human cells a number of CDK7-associated cellular proteins that appear to fall into two classes based on their relative [35S] met...
