This family includes CagL from Helicobacter pylori (Swiss:O25272), a type IV secretion system (T4SS) pilus protein that interacts with several integrins through an helical RGD motif. It shows an all-alpha structure that undergoes specific conformational changes depending on pH variations. These changes also affect the exposure of the RGD motif and therefore modulate its binding capacity to host cell integrins [1-4].
