Abstract
Surface plasmon resonance (SPR) spectroscopy was applied for the first time to study online the association of the blood-brain barrier proteins ZO-1 (zona occludens protein 1) and occludin. The GuK motif of ZO-1 (amino acids 644-812) was identified as the sequence domain that bound to the cytosolic, C-terminal tail of occludin (amino acids 378-521). The nitric oxide (·NO) liberator SIN-1 (3-morpholinosydnonimine) reduced the binding affinity of ZO-1 to occludin, indicating a direct effect of ·NO and NO-related species on the tight junction proteins sealing the blood-brain barrier. We propose that SPR spectroscopy is a novel approach for investigating the interactions of tight junction proteins directly and continuously for pharmacological studies.
