Abstract

Primates have evolved a variety of restriction factors that prevent retroviral replication. One such factor, TRIM5α, mediates a postentry restriction in many Old World primates. Among New World primates, Aotus trivirgatus exerts a similar early restriction mediated by TRIMCyp, a TRIM5–cyclophilin A (CypA) chimera resulting from a CypA retrotransposition between exons 7 and 8 of the TRIM5 gene. Macaca nemestrina do not express TRIM5α; therefore, we asked whether these animals and related Old World primates express TRIMCyp. RT-PCR of total RNA from M. nemestrina and Macaca fascicularis yielded three TRIMCyp amplification products, one of which is predicted to encode a TRIMCyp chimera containing a full-length CypA. Unlike A. trivirgatus , genomic sequencing of M. nemestrina and M. fascicularis identifies a CypA retrotransposition in the 3′ untranslated region of the TRIM5 locus. There is ≈78% homology between the predicted protein sequences of Old World and New World primate TRIMCyp, with most of the differences found in the TRIM5 -derived sequence. Notably, exon 7 is absent from both M. nemestrina and M. fascicularis TRIMCyp. Neither M. nemestrina nor M. fascicularis TRIMCyp could restrict HIV-1 or simian immunodeficiency virus SIVmac in an in vitro infectivity assay. The discovery of TRIMCyp in both M. nemestrina and M. fascicularis indicates that TRIMCyp expression may be more common among Old World primates than previously believed. Convergent evolution of TRIMCyp in both Old World and New World primates suggests that TRIMCyp may have provided evolutionary advantages.
