WebCyclins are transient proteins and show a high turnover during the cell cycle. The mitotic cyclins, A and B, carry an amino acid recognition sequence at their N-terminal, called destruction box, which targets them to the ubiquitination pathway of proteolysis (for this pathway, see Chapter 22).G 1-type cyclins carry a conserved amino acid sequence … Cyclin D is a member of the cyclin protein family that is involved in regulating cell cycle progression. The synthesis of cyclin D is initiated during G1 and drives the G1/S phase transition. Cyclin D protein is anywhere from 155 (in zebra mussel) to 477 (in Drosophila) amino acids in length.
