Immunological and chemical analysis of P6, the carboxyl-terminal fragment of HIV P15.
The first open reading frame of the HIV genome has been identified as the gag gene. The proteins encoded by this gene are p17 as the amino-terminal protein, p24 as the middle peptide, and p15 as the carboxyl-terminal end. A monoclonal antibody recognizing an antigenic determinant on a fragment of p15 has been developed and designated M35/2F8. This monoclonal has been instrumental in radiosequencing the carboxyl-terminal product of p15, p6, and in determining the cleavage site between this protein and the amino-terminal product, p7. By immunoaffinity chromatography it was also possible to purify p6 from HIV lysates and all p6 containing polyproteins from HIV-infected cells. These results gave more insight into the composition and processing of the HIV gag gene.
