Salivary tannin-binding proteins: A foraging advantage for goats?

Tannins are a key chemical defense that plants use against mammalian herbivores. To cope with tannins, many herbivores have evolved salivary tannin-binding proteins that precipitate tannins in forage items, and thus minimize their deleterious effects. In the past, one specific type of salivary tannin-binding protein was identified (proline-rich proteins), and has been found in a range of mammalian species. However, there are other proteins in...
