Molecular 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...
متن کاملCyclin-Dependent Kinases: CAK-handed kinase activation
A protein kinase that activates cyclin-dependent kinases has been identified as a related catalytic subunit in association with a novel cyclin regulatory subunit--it is itself a cyclin-dependent kinase.
متن کاملMAT1-modulated cyclin-dependent kinase-activating kinase activity cross-regulates neuroblastoma cell G1 arrest and neurite outgrowth.
Cyclin-dependent kinase-activating kinase (CAK) regulates cell cycle G1 exit, where cells commonly commit either to proliferate or to differentiate. CAK activity in G1 regulation is determined by its assembly factor and targeting subunit, ménage à trois 1 (MAT1). The precise mechanism of how proliferation/differentiation transition is induced from cancer cell G1 arrest remains unknown. We prese...

15 صفحه اولA distinct cyclin-dependent kinase-activating kinase of Arabidopsis thaliana.
The activation of cyclin-dependent kinases (CDKs) requires phosphorylation of a threonine residue within the T-loop catalyzed by CDK-activating kinases (CAKs). Thus far no functional CAK homologue has been reported in plants. We screened an Arabidopsis cDNA expression library for complementation of a budding yeast CAK mutant. A cDNA, cak1At, was isolated that suppressed the CAK mutation in budd...
