Research Abstract |
Hydrophobic molecule-binding proteins in cytosols were investigated for their structure and function relationship and for cellular distribution. 1. A novel molecular species of rat liver fatty acid binding protein having isoaspartyl residue at position 105 was identified and its physiological significance was investigated. 2. Photo-sensitive affinity labels were synthesized and used for identification of hydrophobic ligand-binding site(s) in fatty acid binding protein. Oleoylimidazolide was also synthesized and shown to be an effective affinity-label for fatty acid binding region. 3. A hydrophobic carcinogenic dye, amino-azobenzene, was administered to rats and binding site for its metabolically activated product was identified. Two other binding proteins were also identified. 4. A new hydrophobic molecule-binding protein was isolated from intestinal epithelium and fully sequenced. 5. Two fatty acid binding proteins were isolated from rat kidneys. It was shown that one of them is a member of lipocalin superfamily and the other heart type fatty acid binding protein.
