In 2007, a study has demonstrated that the interactions between b1 and b2, and between a2 and (b1/b2) are the same for Neuropilin 1 and 2. However a1 interacts differently with the other domains and these interactions are still not really understood. | <p align="justify">In 2007, a study has demonstrated that the interactions between b1 and b2, and between a2 and (b1/b2) are the same for Neuropilin 1 and 2.

The a1 and a2 domains are CUB domains and include <scene name='86/868191/Calcium_binding_site/1'>Calcium binding site</scene>. The ion is coordinated by two carbonyl oxygens from Ala(252)and Ile(253) and by three negatively charged side chains (Glu(195),Asp(209) and Asp(250)). | The a1 and a2 domains are CUB domains and include <scene name='86/868191/Calcium_binding_site/1'>Calcium binding site</scene>.
