Positive selection of primate <i>TRIM5</i> α identifies a critical species-specific retroviral restriction domain

Abstract excerpt

Primate genomes encode a variety of innate immune strategies to defend themselves against retroviruses. One of these, TRIM5alpha, can restrict diverse retroviruses in a species-specific manner. Thus, whereas rhesus TRIM5alpha can strongly restrict HIV-1, human TRIM5alpha only has weak HIV-1 restriction. The biology of TRIM5alpha restriction suggests that it is locked in an antagonistic conflict with the proteins...
