Evolution of multifunctionality through a pleiotropic substitution in the innate immune protein S100A9
J. L. Harman, A. N. Loes, G. D. Warren…·M. J. Harms
The paper shows how a single mutation in S100A9 affects its proinflammatory activity and proteolytic resistance while leaving S100A8/S100A9 antimicrobial activity unchanged, enabling multifunctionality in mammals.
