Název v původním jazyce

Long-term reinfection of the human genome by endogenous retroviruses

Popis výsledku v původním jazyce

Endogenous retrovirus (ERV) families are derived from their exogenous counterparts by means of a process of germ-line infection and proliferation within the host genome. Several families in the human and mouse genomes now consist of many hundreds of elements and, although several candidates have been proposed, the mechanism behind this proliferation has remained uncertain. To investigate this mechanism, we reconstructed the ratio of nonsynonymous to synonymous changes and the acquisition of stop codonsduring the evolution of the human ERV family HERV-K(HML2). We show that all genes, including the env gene, which is necessary only for movement between cells, have been under continuous purifying selection. This finding strongly suggests that the proliferation of this family has been almost entirely due to germ-line reinfection, rather than retrotransposition in cis or complementation in trans, and that an infectious pool of endogenous retroviruses has persisted within the primate lin...
