Abstract:
:The human cyclin H, a protein normally associated with the cyclin-dependent kinase cdk7, was overexpressed in Escherichia coli using a T7 RNA polymerase expression system and further purified to apparent homogeneity. The purified recombinant cyclin H is similar to the endogenous one according to the following criteria: molecular weight, microsequencing and mass spectra studies, ability to interact with cdk7, and regulatory kinase activity. The scale-up of cyclin H purification is described.
