NRP are co-receptors for semaphorins. There are 2 classes of NRP – NRP-1 and NRP-2. NRP-1 has high affinity for semaphorin-3A. NRP-2 has high affinity for semaphorin-3F. Relevance NRP are highly expressed in human neoplasms. Structural highlights NPR structure contains the extracellular domains A1, A2 which bind semaphorin; B1, B2 which bind VEGF and C which is the dimerization region. Ca coordination site. Water molecule are shown as red sphere.
