FliS_cochap is a family of largely Campylobacterales proteins that are co-chaperones for FliS, one of the type III secretion system flagellar chaperones. The HP1076 (Flis_cochap) and FliS complex together prevents premature polymerisation of flagellins and is critical for flagellar assembly and bacterial colonisation. The HP1076 shows co-chaperone activity that promotes protein folding of FliS with mutations in the flagellin binding pocket and enhances the chaperone activity of FliS [1].	Domain
