Evolution of the antiretroviral restriction factor TRIMCyp in Old World primates.

Abstract excerpt

The retroviral restriction factor TRIMCyp, which is a fusion protein derived from the TRIM5 gene, blocks replication at a post-entry step. Among Old World primates, TRIMCyp has been found in four species of Asian macaques, but not in African monkeys. To further define the evolutionary origin of Old World TRIMCyp, we examined two species of baboons (genus Papio) and three additional macaque species, including M....
