We investigate the impact of environment heterogeneity on mutant fixation in spatially structured populations with demes on the nodes of a graph. When migrations between demes are frequent, we find that environment heterogeneity can amplify natural selection and simultaneously accelerate mutant fixation and extinction, thereby fostering the quick fixation of beneficial mutants. We demonstrate this effect in the star graph, and more strongly in the line graph. We show that amplification requires mutants to have a stronger fitness advantage in demes with stronger migration outflow, and that this condition allows amplification in more general graphs. As a baseline, we consider circulation graphs, where migration inflow and outflow are equal in each deme. In this case, environment heterogeneity has no impact to first order, but increases the fixation probability of beneficial mutants to second order. Finally, when migrations between demes are rare, we show that environment heterogeneity can also foster amplification of selection, by allowing demes with sufficient mutant advantage to become refugia for mutants.</p>","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":" ","pages":""},"PeriodicalIF":15.7,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147856768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show here that proton efflux through the endosomal Na⁺/H⁺ Exchanger (NHE6) activates the late endosome master regulator Rab7. Importantly, NHE6 is mutated in the childhood neurologic disorder Christianson Syndrome. We demonstrate that NHE6 interacts with the Rab7 GTPase-activating protein (GAP) TBC1D5 in a complex with Rab7 on the late endosome. This interaction and proton efflux are both required for Rab7 activation. TBC1D5 is potently inactivated with decreasing pH. A conserved histidine in the TBC1D5 GAP domain mediates pH-dependence. Furthermore, we show that neurons from mice engineered with a selective defect in NHE6 proton efflux exhibit blocked endosome maturation and disrupted Rab7 GTP-GDP cycling. In addition, knock-down of TBC1D5, thereby reducing Rab7 GAP activity, in NHE6 mutant neurons rescues Rab7 GTP-GDP cycling and endosome maturation. Finally, we present a biophysical model of proton signaling through acidic pH microdomains within the NHE6-TBC1D5-Rab7 protein complex upon endosome acidification. In conclusion, our studies provide evidence supporting a mechanism involving \"inside-out\" proton signaling, whereby lumen acidification drives endosome maturation through pH-dependent Rab GTPase cycling.
