KAPs Off for HIV-1 Integration

Integration of reverse transcribed HIV-1 DNA into the host genome, catalyzed by HIV-1 integrase, represents an obligate step in establishing productive viral infection. Allouch et al. (2011) identify KAP1 (TRIM28) as an interaction partner of acetylated integrase. KAP1, in complex with HDAC1, represses HIV-1 integration through specific deacetylation of HIV-1 integrase.
