Domain relationships



ERp29 (also known as ERp28 and ERp31) is a ubiquitously expressed endoplasmic reticulum protein found in mammals [PMID: 11435111]. This protein has an N-terminal thioredoxin-like domain, which is homologous to the domain of human protein disulphide isomerase (PDI). ERp29 may help mediate the chaperone function of PDI. The C-terminal Erp29 domain has a 5-helical bundle fold. ERp29 is thought to form part of the thyroglobulin folding complex [PMID: 11884402].

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. The C-terminal domain of Wind is thought to provide a distinct site required for interaction with its substrate, Pipe [PMID: 12941941].
