Abstract excerpt
Alternatively spliced beta-neurexins (beta-NRXs) and neuroligins (NLs) are thought to have distinct extracellular binding affinities, potentially providing a beta-NRX/NL synaptic recognition code. We utilized surface plasmon resonance to measure binding affinities between all combinations of alternatively spliced beta-NRX 1-3 and NL 1-3 ectodomains. Binding was observed for all beta-NRX/NL pairs. The presence of...
