Subcellular localization of avian sarcoma virus and human immunodeficiency virus type 1 integrases.
The composition and subcellular trafficking of subviral preintegration complexes are reported to vary among the different retroviruses. The process by which the avian sarcoma virus (ASV) preintegration complex gains access to target chromatin remains unknown. Here we report that ASV integrase (IN) expressed as a fusion to beta-galactosidase accumulates in the nuclei of transfected COS-1 cells. ...
متن کاملIdentification of positive and negative splicing regulatory elements within the terminal tat-rev exon of human immunodeficiency virus type 1.
The requirement of human immunodeficiency virus type 1 to generate numerous proteins from a single primary transcript is met largely by the use of suboptimal splicing to generate over 30 mRNAs. To ensure that appropriate quantities of each protein are produced, there must be a signal(s) that controls the efficiency with which any particular splice site in the RNA is used. To identify this contr...
متن کاملConserved functional organization of the human immunodeficiency virus type 1 and visna virus Rev proteins.
Visna virus encodes a posttranscriptional regulatory protein that is functionally analogous to the Rev trans activator of human immunodeficiency virus type 1. Here, we demonstrate that the known functional organization of the human immunodeficiency virus type 1 Rev trans activator is shared by the distantly related visna virus Rev protein. In particular, both Rev proteins contain an N-terminal ...
متن کاملQuantification Analysis of Dot Blot Assays for Human Immunodeficiency Virus Type 1 and 2 Antibodies
Objective Dot Blot (DB) assay provides highly specific results, but usually not reliable for quantification of antibody production. The need for a more objective DB assay to provide a better definition of the immune status, against HIV antigens, promoted this study to be done to develop a quantitative DB assay. Material and Methods Dot blot (DB) strips for antibodies directed to human immuno...
متن کاملCo-expression of a trans-dominant negative mutant of the human immunodeficiency virus type 1 (HIV-1) Rev protein affects the Rev-dependent splicing pattern and expression of HIV-1 RNAs.
Trans-dominant negative mutants of the human immunodeficiency virus type 1 (HIV-1) regulatory protein Rev inhibit the function of wild-type Rev in a dose-dependent manner. This was previously shown to be caused by nuclear retention of the wild-type protein. In the present work, further analysis of the trans-dominant negative effect was performed using cotransfection experiments with different c...
