Deskripsi

HIV-1 integrase (IN) binds the host factor INI1/SMARCB1, which is required at multiple stages of HIV-1 replication. Here, the authors show that the same IN residues are involved in INI1 and RNA binding and in influencing particle morphogenesis and suggest that the IN-binding INI1 domain is structurally similar to HIV TAR RNA.
