Abstract Background Human T-cell leukemia virus HTLV -1 and -2 are deltaretroviruses that infect a wide range of cells. Glut1 the major vertebrate glucose transporter has been shown to be the HTLV Env receptor. While it is well established that the extracellular surface component SU of the HTLV envelope glycoprotein Env harbors all of the determinants of interaction with the receptor identification of SU subdomains that are necessary and sufficient for interaction with the receptor as well as critical amino acids therein remain to be precisely defined. Although highly divergent in the rest of their genomes HTLV and murine leukemia virus MLV Env appear to be related and based on homologous motifs between the HTLV and MLV SU we derived chimeric HTLV MLV Env and soluble
