New paper: Structural evolution of proline-rich protein genes in primate saliva

Out in Molecular Biology and Evolution, led by Aguado and Pajic, with Charikleia Karageorgiou, Sarah Kassem and Stefan Ruhl among the authors. We traced the structural evolution of the proline-rich protein genes across primates and what it means for salivary defenses — another piece of the long-running question of why primate saliva looks so different from species to species. The paper is in Molecular Biology and Evolution (msag224).
