Gene: CCNH (cyclin H) Homo sapiens
Symbol: CCNH
Name: cyclin H
Description: Contributes to DNA-dependent ATPase activity and RNA polymerase II CTD heptapeptide repeat kinase activity. Involved in positive regulation of transcription by RNA polymerase II; protein stabilization; and transcription by RNA polymerase II. Localizes to cyclin-dependent protein kinase activating kinase holoenzyme complex and transcription factor TFIIH holo complex.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: CAK; CAK complex subunit; CDK-activating kinase complex subunit; CycH; cyclin-dependent kinase-activating kinase complex subunit; cyclin-H; MO15-associated protein; p34; p37
