A naturally acquired human monoclonal antibody recognizes proteins expressed at different stages of the Plasmodium falciparum life cycle through affinity-matured homotypic interactions with glutamate-rich repeats.

Electric signals produced by weakly electric gymnotiform fish, long seen as communication attempts, may also serve to localize conspecifics, revealing a distinct functional role.

N‑terminus of MSL1 protein, involved in dosage compensation in Drosophila, is required for the interaction with non-coding roX2 RNA and the assembly of the complex on the male X chromosome.

Plasmodium parasites have repurposed the heme oxygenase scaffold from its canonical heme-degrading function to fulfill an essential and adaptive role in gene expression within the apicoplast organelle.
