Abstract: Peptides comprising an Rpt1 domain of an INI1/hSNF5 which inhibit HIV-1 production in a human cell, and vectors encoding those peptides are provided. Also provided are methods of inhibiting HIV-1 production in a cell, or spread of the HIV-1 to another cell, by treating the cells with the above peptides or vectors. Other methods of inhibiting HIV-1 production in a cell, or spread of the HIV-1 to another cell, by inhibiting production of INI1/hSNF5 are provided. Additionally, methods of determining whether a test compound inhibits HIV-1 virion production in a mammalian cell, or spread of the HIV-1 to another cell, are provided. Those methods comprise determining whether the test compound inhibits the production of INI1/hSNF5 or disrupts the interaction of HIV-1 integrase with INI1/hSNF5.

Abstract: A mutated mycobacterium selected from the class consisting of mutated M. bovis-BCG, mutated M. tuberculosis, and mutated M. leprae. The mutation of M. bovis-BCG, M. tuberculosis, or M. leprae is preferably effected through an insertional mutation of a mycobacterial gene. The insertional mutagenesis may be effected, for example, through illegitimate recombination or by a mycobacterial transposon. Such mutated mycobacteria may then be transformed with an expression vector(s) containing a complement gene to the gene which is mutated, and preferably also including a heterologous gene.

Abstract: Upon entry into a host cell, retroviruses direct the reverse transcription of the viral RNA genome and the establishment of an integrated proviral DNA. The retroviral integrase protein (IN) is responsible for the insertion of the viral DNA into host chromosomal targets. The IN catalyzes two specific biochemical reactions: (i) cleavage of the 3′termini of the viral DNA to produce 3′-OH ends, and (ii) joining of the two newly generated 3′-termini to the 5′-phosphates on each strand of the target sequence in a concerted strand-transfer reaction. The yeast two-hybrid system was used to identify a novel human gene product, herein designated integrase interactor 1 or INI-1, that binds tightly to the human immunodeficiency virus type 1 (HIV-1) integrase in vitro.

The yeast two-hybrid system was used to identify a novel human gene product, herein designated integrase interactor 1 or INI-1, that binds tightly to the human immunodeficiency virus type 1 (HIV-1) integrase in vitro. Approximately 10.sup.6 complementary DNAs (cDNAs) of the HL60 macrophage-monocytic cell line were expressed as GAL4AC (activation domain) fusions and tested for coactivation of a reporter gene together with a GAL4DB (DNA binding) IN fusion.
