Identification and
characterization of a lipophorin receptor from the teratocytes
of Dinocampus coccinellae
National Institute of Sericultural and Entomological Science, Owashi 1-2, Tsukuba, Ibaraki 305 8634, Japan Teratocytes of Dinocampus coccinellae synthesize a teratocyte-specific polypeptide of 540 kDa. The teratocytes exhibited a lipophorin binding site at the cell surface. It was demonstrated using avidin biotin system. The receptor protein has an apparent molecular weight of 94 kDa in SDS-PAGE under non-reducing conditions and was sensitive to treatment with EDTA and Suramin. The importance of the lipophorin receptor and its role in relation to its host, Coccinellid is discussed. Index terms:Teratocyte-specific protein,lipid uptake, host-parasitoid relationship, Coccinella septumpunctata.
