Regulated progression through the cell cycle requires sequential expression of a family of proteins called cyclins. Upon their induction, cyclins form complexes with specific cyclin-dependent kinases (CDKs), creating active holoenzymes that phosphorylate target proteins required for cell-cycle progression. In humans, the CDK/Cyclin H complex regulates the CDK-activating kinase (CAK). CAK is involved in activation of RNA polymerase II when complexed with the core-TFIIH basal transcription factor, allowing for elongation of transcripts. However, the function of the Cyclin H ortholog in zebrafish has not yet been isolated. One study has shown Cyclin H to be present throughout early stages of development, and experiments with defective Cyclin H suggest that it plays a vital role in this area.
