[https://www.uniprot.org/uniprot/CCNH_HUMAN CCNH_HUMAN] Regulates CDK7, the catalytic subunit of the CDK-activating kinase (CAK) enzymatic complex. CAK activates the cyclin-associated kinases CDK1, CDK2, CDK4 and CDK6 by threonine phosphorylation. CAK complexed to the core-TFIIH basal transcription factor activates RNA polymerase II by serine phosphorylation of the repetitive C-terminus domain (CTD) of its large subunit (POLR2A), allowing its escape from the promoter and elongation of the transcripts. Involved in cell cycle control and in RNA transcription by RNA polymerase II. Its expression and activity are constant throughout the cell cycle.<ref>PMID:7533895</ref> <ref>PMID:10024882</ref>

The crystal structure of human cyclin H has been solved at 2.6 A resolution by the MIR method and refined to an R-factor of 23.1%. The core of the molecule consists of two helical repeats adopting the canonical cyclin fold already observed in the structures of cyclin A [Brown et al. (1995) Structure 3, 1235-1247; Jeffrey et al. (1995) Nature 376, 313-320; Russo et al. (1996) Nature 382, 325-331] and TFIIB [Nikoilov et al. (1995) Nature 377, 119-128]. The N-terminal and C-terminal residues form a new domain built on two long helices interacting essentially with the first repeat of the molecule.
