This is the N-terminal domain of ARMET proteins (also known as mesencephalic astrocyte-derived neurotrophic factor (MANF) or arginine-rich protein) [1,2,3], a saposin-like domain consisting of five alpha-helices with three cystein bridges that stabilises the globular "closed leaf" conformation [2,3]. ARMET is a small protein of approximately 170 residues which contain four di-sulfide bridges that are highly conserved from nematodes to humans. It is a soluble protein resident in the endoplasmic reticulum and induced by ER stress. It appears to be involved with dealing with mis-folded proteins in the ER, thus in quality control of ER stress [1].
