Web23 de out. de 2014 · • The regulated activity of CDKs is essential for the transitions from G1 to S and from G2 to M, and for the entry of nondividing cells into the cell cycle. • The transition from G1 to S requires a set of cyclins ( G1 cyclins) different from those required in the transition from G2 to mitosis, where mitotic cyclins activate the CDKs . WebUnlike CDKs, which are highly homolo-gous, cyclins are a remarkably diverse family of proteins, ranging in size from approximately 35 to 90 kDa. 1-4 Sequence homology among the cyclins tends to be concentrated in a 100–amino acid domain known as the cyclin box, which is necessary for CDK binding and activa-tion.
