ERp29 (Swiss:P52555) is a ubiquitously expressed endoplasmic reticulum protein, and is involved in the processes of protein maturation and protein secretion in this organelle [1,2]. The protein exists as a homodimer, with each monomer being composed of two domains. The N-terminal domain featured in this family is organised into a thioredoxin-like fold that resembles the a domain of human protein disulphide isomerase (PDI) [2]. 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 [2]. The N-terminal domain is exclusively responsible for the homodimerisation of the protein, without covalent linkages or additional contacts with other domains [2].	Domain
