PG - 334-6 AB - The ability of cyclophilin to bind a panel of recombinant HIV-gag proteins was assessed using sensitive, quantitative, sandwich enzyme-linked immunosorbant assays (ELISAs). Significantly higher binding to cyclophilin was observed when recombinants contained at least 12 carboxy-terminal amino acids of p17 in addition to p24 sequences. These results indicate that the carboxy-terminus of p17 is important for optimal binding of cyclophilin to p24 and support the theory that cyclophilin acts on the uncleaved HIV-1 gag (p17-p24) precursor.
