RBM39 and infection: Although showing little effect on its own, rbm-39(S294L) significantly restored body size (Fig. 2d), developmental rate (Fig. 2e) and infection tolerance (Extended Data Fig. 2j), and diminished rnp-6(G281D) lifespan extension (Fig. 2f), suggesting that rbm-39(S294L) ameliorates rnp-6(G281D) function.
