HIV protein: integrase
Interaction type: imported by
Description: Some reports indicate a possible role for the interactions between karyopherin alpha and beta with HIV-1 integrase in the nuclear import of HIV-1 preintegration complexes (PIC), while other reports indicate integrase is not involved in PIC nuclear import
