The book Gene Duplication consists of 21 chapters divided in 3 parts: General Aspects, A Look at Some Gene Families and Examining Bundles of Genes. The importance of the study of Gene Duplication stems from the realization that the dynamic process of duplication is the “sine qua non” underlying the evolution of all living matter. Genes may be altered before or after the duplication process thereby undergoing neofunctionalization, thus creating in time new organisms which populate the Earth.
Osaka (Chapter I) suggests that similarities in amino acid sequences exhibited by paralogous proteins prove that evolution proceeds via in toto gene duplication. If the ancestral and the newly created gene perform the same function, the new gene would be labeled a subfunctional gene. It should be added that such a duplicated gene encoding an identical product might also be engaged by different cellular regulatory signals (e.g. methylation of nucleotide sites) which in turn, could hamper the expression of such a duplicated gene. (See e.g. Woody et al. Chapter 3). If this duplicated gene subsequently undergoes mutations that allow a function for the new gene that is different from the parent gene (neofunctionalization) that would represent a far more positive evolutionary event. The first three chapters in this book focus on such in toto gene duplications whereby in evolutionary time neofunctionalization could have taken hold. There are also several specific cicumscribed examples given in this book. (See e.g. Majee&Kaur, Chapter 12). Undoubtedly, duplication contributes substantially to the formation of new genes. But there is a caveat: In time, the majority of duplicated genes mutates into oblivion.
In recent years, however, attention has been paid to another possible path for creating a new gene: The formation of the chimeric gene, a gene immediately ready for a new function. Such a gene might result from altering the position of spliced introns, or more likely from retropositioning of a new encoding domain into the gene: I.e. partial gene duplications and combination. It is obvious that such processes are particularly suited for the creation of genes encoding multi-domain proteins and that they may accelerate considerably the natural process of neofunctionalization. (See Hatje et al.Chapter 4; Friedberg, Chapter 5; Toll-Riera et al. Chapter 6 and Iwashita et al. Chapter 21). Retrotransposons are capable of promoting such segmental duplications.
”Retroduplication” contributes significantly to the formation of new genes. These genes, in turn may also be duplicated and eventually be erased into oblivion by mutations.
