title: A chicken transferrin binding protein is heat shock protein 108.
abstract: A previously described transferrin binding protein from chicken oviduct has been identified as a heat shock protein, HSP108, by microsequencing of RP-HPLC purified tryptic peptides. The protein purified from oviduct by SDS-PAGE or from liver by ovotransferrin-affinity chromatography reacts with a monoclonal antibody raised against HSP108. The cDNA sequence predicts of KDEL peptide at the carboxyl terminus, but the protein does not react with anti-KDEL monoclonal antibodies, suggesting that HSP108 is processed in a way that eliminates the KDEL epitope.
