Sequence identity in domains I, II, and III (see Figure 3) was determined after pairwise alignment (clam cyclin A, Swenson et al., 1986; human cyclin B, Pines and Hunter, 1989; S. pombe cdc13, Booher and Beach, 1988; Drosophila cyclin C; S. cerevisiae Cln1 and Cln3, Hadwiger et al., 1989; and human prad1, Motakura et al., 1991).
