[[Neurexin|Neurexins]] (NRXN) are a family of presynaptic proteins which bind to the postsynaptic [[Neuroligin]] (NLGN) to form a complex which attaches neurons.  The NRXN family contains 4 members which are numbered 1 to 4.  The α-NRXN contains 6 homologous LNS domains while the β-NRXN contains only LNS6. The images at the left and at the right correspond to one representative NRXN, ''i.e.'' the crystal structure of mouse β-neurexin 1 ([[3bod]]).
