Cellular TRIM33 restrains HIV-1 infection by targeting viral integrase for proteasomal degradation
HIV-1 integration into host DNA is mediated by the viral integrase (IN). Here, using siRNA screen and high-content microscopy, the authors identify the host E3 RING ligase TRIM33 to affect IN stability and show that TRIM33 prevents viral integration by triggering IN proteasome-mediated degradation.
