The NRXN family contains 4 members which are numbered 1 to 4[1]. The NRXN-α contains 6 homologous LNS domains while the NRXN-β contains only LNS6. See: Neurodevelopmental Disorders Neuroligin-Neurexin Interaction Relevance NRXN sequence variants may contribute to autism spectrum disorder and other cognitive diseases[2]. Structural highlights The is mediated by a [3]. Water molecules are shown as red spheres.
