Throughout evolution, development of a functional protein is an unlikely event. Once a successful solution to a chemical problem (eg monooxygenation) is achieved, most likely the solution is repeated and modified to suit any new metabolic task. This phenomenon is now known to have occurred for numerous multigene families [l] by means of duplication of the ancestral gene and subsequent modification of extra genes for evolving functions. Gene duplication is believed to occur by gene conversion and/or unequal crossing-over [1, 2]. As the result of this recent discovery in molecular biology, there are two immediate conclusions.(a) In a given species, there exist families of proteins with strikingly similar structure. Insulin, insulin-like growth factor, relaxin, and nerve growth factor, for example, are four insulin-related growth factors within the same multigene family whose genes have evolved from a common ancestral gene [3-51. Albumin and cu-fetoprotein evoke different antibodies yet have evolved from a common ancestral gene [6, 7]. The genes for prolactin, growth hormone and chorionic somatomammotropin probably have arisen from a single ancestral gene [S]. The genes that encode a single protein may be arranged in tandem fashion with spacer regions between each gene on the same chromosome (as in the case of globin 19. lo], interferon [ll] or albumin and ct+ fetoprotein [12]) or on two or more chromosomes, as in the case of the immunoglobulins [13].‘Silent’genes (or pseudogenes’) for cu-globin have been described on a chromosome distinct from that containing the regular a-globin multigene family [141.(b) Among many different species, homologous enzymes and other proteins are st~ cturally similar. A corollary to this conclusion is that the genes encoding homologous proteins will have considerable nucleotide sequence homology. By DNA hybridization techniques, therefore, the growth hormone mRNA in cow, rat and human were shown to be related [15]. The yeast cytochrome c gene was used for isolating the rat cytochrome c gene [16]. The mouse PI-450 gene was used to isolate the rat PI-450 gene [17].
