Abstract
Lipid binding activities of the P2 protein in peripheral nerve myelin were examined using retinoic acid, retinol and oleic acid as ligands. The P2 protein showed the specific binding affinity to both of retinoic acid and retinol. The binding site of these ligands was suggested to be similar. In addition, the high binding activity of the P2 protein with oleic acid was also observed. The ligands specificities of the P2 protein are clearly different from those of cellular retinoic acid binding protein (CRABP), cellular retinol binding protein (CRBP), and Z protein. In amino terminal sequence, however, the P2 protein contained considerable homologous structure to these lipid binding proteins. Therefore, the P2 protein and these lipid binding proteins may belong to a family of structurally related proteins evolved from a common ancestral gene.
