 35-157 3.83e-66

Protein Disulfide Oxidoreductases and Other Proteins with a Thioredoxin fold; The thioredoxin (TRX)-like superfamily is a large, diverse group of proteins containing a TRX fold. Many members contain a classic TRX domain with a redox active CXXC motif. They function as protein disulfide oxidoreductases (PDOs), altering the redox state of target proteins via the reversible oxidation of their active site dithiol. The PDO members of this superfamily include the families of TRX, protein disulfide isomerase (PDI), tlpA, glutaredoxin, NrdH redoxin, and bacterial Dsb proteins (DsbA, DsbC, DsbG, DsbE, DsbDgamma). Members of the superfamily that do not function as PDOs but contain a TRX-fold domain include phosducins, peroxiredoxins, glutathione (GSH) peroxidases, SCO proteins, GSH transferases (GST, N-terminal domain), arsenic reductases, TRX-like ferredoxins and calsequestrin, among others.

 35-157 3.83e-66

ERp29, N-terminal domain; ERp29 is a ubiquitously expressed endoplasmic reticulum protein, and is involved in the processes of protein maturation and protein secretion in this organelle. The protein exists as a homodimer, with each monomer being composed of two domains. The N-terminal domain featured in this family is organized into a thioredoxin-like fold that resembles the a domain of human protein disulphide isomerase (PDI). However, this domain lacks the C-X-X-C motif required for the redox function of PDI; it is therefore thought that ERp29's function is similar to the chaperone function of PDI. The N-terminal domain is exclusively responsible for the homodimerization of the protein, without covalent linkages or additional contacts with other domains.

 38-151 2.15e-62

PDIa family, endoplasmic reticulum protein 29 (ERp29) subfamily; ERp29 is a ubiquitous ER-resident protein expressed in high levels in secretory cells. It forms homodimers and higher oligomers in vitro and in vivo. It contains a redox inactive TRX-like domain at the N-terminus, which is homologous to the redox active TRX (a) domains of PDI, and a C-terminal helical domain similar to the C-terminal domain of P5. The expression profile of ERp29 suggests a role in secretory protein production distinct from that of PDI. It has also been identified as a member of the thyroglobulin folding complex. The Drosophila homolog, Wind, is the product of windbeutel, an essential gene in the development of dorsal-ventral patterning. Wind is required for correct targeting of Pipe, a Golgi-resident type II transmembrane protein with homology to 2-O-sulfotransferase.

ERp29 and ERp38, C-terminal domain; composed of the protein disulfide isomerase (PDI)-like proteins ERp29 and ERp38.

ERp38 is a P5-like protein, first isolated from alfalfa (the cDNA clone was named G1), which contains two redox active TRX domains at the N-terminus, like human P5. However, unlike human P5, ERp38 also contains a C-terminal domain with homology to the C-terminal domain of ERp29. It may be a glucose-regulated protein. The function of the all-helical C-terminal domain of ERp29 and ERp38 remains unclear. The C-terminal domain of Wind is thought to provide a distinct site required for interaction with its substrate, Pipe.

 41-147 3.12e-11

Protein Disulfide Isomerase (PDIa) family, redox active TRX domains; composed of eukaryotic proteins involved in oxidative protein folding in the endoplasmic reticulum (ER) by acting as catalysts and folding assistants. Members of this family include PDI and PDI-related proteins like ERp72, ERp57 (or ERp60), ERp44, P5, PDIR, ERp46 and the transmembrane PDIs. PDI, ERp57, ERp72, P5, PDIR and ERp46 are all oxidases, catalyzing the formation of disulfide bonds of newly synthesized polypeptides in the ER. They also exhibit reductase activity in acting as isomerases to correct any non-native disulfide bonds, as well as chaperone activity to prevent protein aggregation and facilitate the folding of newly synthesized proteins. These proteins usually contain multiple copies of a redox active TRX (a) domain containing a CXXC motif, and may also contain one or more redox inactive TRX-like (b) domains. Only one a domain is required for the oxidase function but multiple copies are necessary for the isomerase function. The different types of PDIs may show different substrate specificities and tissue-specific expression, or may be induced by stress. PDIs are in their reduced form at steady state and are oxidized to the active form by Ero1, which is localized in the ER through ERp44. Some members of this family also contain a DnaJ domain in addition to the redox active a domains; examples are ERdj5 and Pfj2. Also included in the family is the redox inactive N-terminal TRX-like domain of ERp29.
