This Brief summarizes the current research on the novel BRICHOS domain, which is a chaperone domain found in a variety of proteins and is shown to exhibit anti-amyloidogenic chaperone-like functions. The BRICHOS domain is defined from sequence similarities, lacks established physiological function(s) and is found about 10 distantly related pro-protein families, several of which are associated with human disease. In this work, the authors review the mechanism by which BRICHOS inhibits Aβ aggregation and examine recent results from in vivo experiments where BRICHOS inhibits Aβ...
