title: Cloning and expression of interleukin-3 genes of chimpanzee and New World monkeys.
abstract: Interleukin-3 (IL-3) genes were cloned from chimpanzee (Pan troglodytes), tamarin (Saguinus oedipus) and marmoset (Callithrix jacchus) and expressed in COS cells. Although the IL-3 gene structure is well conserved in these primate species, sequence analysis revealed extensive base substitutions. The chimpanzee IL-3 protein, which is highly homologous (98.5% identity) to human IL-3, stimulated proliferation of human cells dependent on IL-3. In contrast, due to the numerous amino acid substitutions in the New World monkey IL-3 species, no stimulation of human cells was observed, illustrating the extensive evolutionary divergence of IL-3.
