ZCCHC3 and infection: Notably, ZCCHC3 also suppressed the infection of other retroviruses, such as SIV from rhesus macaques (SIVmac), feline immunodeficiency virus (FIV), equine infectious anemia virus (EIAV), and murine leukemia virus (MLV) (Figure 1E), suggesting that ZCCHC3 inhibits the infection of a broad range of retroviruses.
