In response to a rise in ecdysteroid titre, fat body cells of insect larvae take up storage proteins from the haemolymph by receptor-mediated endocytosis. Here we show that the receptor responsible for incorporation of the major haemolymph protein arylphorin of the blowfly, Calliphora vicina, is subject to an unusual posttranslational processing that involves three distinct cleavage steps. After the removal of a 17-amino-acid signal peptide, a receptor precursor of 141 kDa is released. Before… CONTINUE READING
