Multiple effects of mutations in human immunodeficiency virus type 1 integrase on viral replication.
The integration of a DNA copy of the human immunodeficiency virus type 1 (HIV-1) genome into a chromosome of an infected cell is a pivotal step in virus replication. Integration requires the activity of the virus-encoded integrase, which enters the cell as a component of the virion. Results of numerous mutagenesis studies have identified amino acid residues and protein domains of HIV-1 integras...
متن کاملUncoupling human immunodeficiency virus type 1 Gag and Pol reading frames: role of the transframe protein p6* in viral replication.
Apart from its regulatory role in protease (PR) activation, little is known about the function of the human immunodeficiency virus type 1 transframe protein p6* in the virus life cycle. p6* is located between the nucleocapsid and PR domains in the Gag-Pol polyprotein precursor and is cleaved by PR during viral maturation. We have recently reported that the central region of p6* can be extensive...
متن کاملIn vitro selection of RNAs that bind to the human immunodeficiency virus type-1 gag polyprotein.
RNA ligands that bind to the human immunodeficiency virus type-1 (HIV-1) gag polyprotein with 10(-9) M affinity were isolated from a complex pool of RNAs using an in vitro selection method. The ligands bind to two different regions within gag, either to the matrix protein or to the nucleocapsid protein. Binding of a matrix ligand to gag did not interfere with the binding of a nucleocapsid ligan...
متن کاملVenom Components of Iranian Scorpion Hemiscorpius lepturus Inhibit the Growth and Replication of Human Immunodeficiency Virus 1 (HIV-1)
Background: During the recent years, significant progress has been achieved on development of novel anti-viral drugs. Natural products are assumed as the potential sources of novel anti-viral drugs; therefore, there are some previous studies reporting the anti-viral compounds from venomous animals. Based on the significant value for tracing of non-toxic anti-viral agents from natural resources,...
متن کاملProgression of early steps of human immunodeficiency virus type 1 replication in the presence of an inhibitor of viral protease.
We have evaluated a possible role for human immunodeficiency virus type 1 protease during early steps of replication. For these studies, a specific inhibitor of human immunodeficiency virus protease, Ro31-8959, was used. Synthesis of viral cDNA, its integration into cellular DNA, and its transcription were determined during a one-step, acute infection of MT-4 cells. No consistent difference in ...
