Recently, it has been recognised that the amino acid motif VQL(N/V)ES is shared between the second conserved domain of human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein (gp120) and the first framework (FW1) of human IgG heavy chain variable region (subgroup III) (VHIII). We have found that nucleotide sequence corresponding to this motif contains some recombination elements characteristic for the genes of human Ig heavy-chain variable region. The possible role of the Ig recombination elements in HIV-1 envelope gene variability, AIDS pathogenesis and vaccine design is discussed.
