Differential phosphorylation activities of CDK-activating kinases in Arabidopsis thaliana.

Abstract

Activation of cyclin-dependent kinases (CDKs) requires phosphorylation of a threonine residue within the T-loop by a CDK-activating kinase (CAK). Here we isolated an Arabidopsis cDNA (CAK4At) whose predicted product shows a high similarity to vertebrate CDK7/p40(MO15). Northern blot analysis showed that expressions of the four Arabidopsis CAKs (CAK1At… (More)
