WebJul 14, 2024 · Gene duplication is a crucial process involved in the appearance of new genes and functions. It is thought to have played a major role in the growth of enzyme families and the expansion of metabolism at the biosphere’s dawn and in recent times. Here, we analyzed paralogous enzyme content within each of the seven enzymatic classes for … WebFeb 1, 2004 · The evolutionary significance of whole genome duplications is that a swath of new genes and modules (e.g., Hox genes; MADS-Box genes) is thought to provide new potential for diversification-either ...
WebFeb 10, 2024 · These factors could thus potentially confound any differences in sequence or expression divergence between gene categories. However, as far as we are aware, the relative importance of gene function and other factors for coding sequence or expression divergence of immune genes has not been explicitly addressed. WebTo estimate the functional divergence between a pair of paralogous genes, we consider the gene set annotations assigned to each paralog. Ordinarily, we assume that paralogs …
WebFeb 21, 2024 · One type of subfunctionalization takes place by complementary coding sequence changes between duplicated genes, leading to their functional divergence at the protein level, and eventually resulting in division of multiple functions of the progenitor gene.
