ClustalX alignment of glucose transporter family sequences. Amino acid sequences of the known glucose transporter family members were aligned using ClustalX. The potential PtdOH binding motif SQWLxRML (shown by boxed region) is only found in GLUT4, located in the cytoplasmic loop between helices two and three. Lower panel shows the alignment of the GLUT4 region with the phage display peptide, with homologous residues in bold type.
