Charged residues flanking aggregation-prone regions play a role in protein folding and prevention of aggregation. In this issue of The EMBO Journal, Houben et al exploit the role of such charged gatekeepers in aggregation suppression and find that negative charges are more effective than positive ones. Strikingly, the prominent Hsp70 chaperone has a strong preference for the less effective, basic gate keepers. This implies co-adaptation of chaperone specificity and composition of protein sequences in evolution. © 2020 The Authors.T
