title: [Molecular cloning and multifunctions of membrane-associated 3,5,3'-triiodo-L-thyronine binding protein with protein disulfide isomerase activity].
abstract: The protein or cDNA sequencing revealed that the membrane-associated 3,5,3'-triiodo-thyronine binding protein (T3BP) acts as a multifunctional protein:protein disulfide isomerase (PDI) catalyzing isomerization of intra- and inter-molecular disulfide bridge in the proteins, beta-subunit of prolyl 4-hydroxylase catalyzing the formation of 4-hydroxyproline in collagen molecules, glycosylation site binding protein which is a component of oligosaccharyl transferase transferring oligosaccharide chains to the asparagine residues of Asn-X-Ser/Thr site in nascent polypeptide, and a component of triglyceride transfer protein complex involved in the transfer unit of triglyceride, cholesteryl ester and phosphatidylcholine between biomembranes. The functions of 55 k-T3BP/PDI, mainly involved in important post-translational modifications, are discussed in relation to the domain structure of the molecule.
