Cyclin H Recombinant, Human

This protein belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. This cyclin forms a complex with CDK7 kinase and ring finger protein MAT1. The kinase complex is able to phosphorylate CDK2 and CDC2 kinases, thus functions as a CDK-activating kinase (CAK). This cyclin and its kinase partner are components of TFIIH, as well as RNA polymerase II protein complexes. They participate in two different transcriptional regulation processes, suggesting an important link between basal transcription control and the cell cycle machinery. \n\nTag/Fusion Partner: His-Tag at N-terminus\n\nApplications: Suitable for use in Western Blot, ELISA as an Antigen, Ligand, or Assay Standard. Other applications not tested.\n\nQuality Control: SDS-PAGE Storage and Stability: May be stored at 4 degrees C for short-term only. For long-term storage, aliquot to avoid repeated freezing and thawing and freeze at -70 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Aliquots are stable for at least 12 months. \n\nImportant note: This recombinant enzyme has NOT been tested with regard to biological activity.
