Protein sequence evolution underlies interspecies incompatibility of a cell fate determinant

Emily L. Rivard, John R. Srouji, Anastasia Repouliou, Cassandra G. M. Extavour

This study identifies the OSK domain of D. virilis Oskar as the cause of interspecies incompatibility with D. melanogaster Oskar, linking protein sequence evolution to functional divergence.

The LOTUS domain of Oskar promotes localisation of both protein and mRNA components of Drosophila germ plasm

Anastasia Repouliou, John R. Srouji, Emily L. Rivard…·Cassandra G. M. Extavour

The paper tests Oskar variants in vivo to assess their role in germ plasm assembly, finding that the LOTUS domain is critical for mRNA recruitment despite the current model attributing this function to the OSK domain.
