Figure Legend Snippet: ( A ) Schematic of biolayer interferometry (BLI) setup for Tspan12-Norrin binding: Tspan12 lacking the C-terminal tail (∆C), inserted into biotinylated nanodiscs, is immobilized on a streptavidin-coated biosensor, and Norrin association and dissociation are monitored in real time. ( B ) BLI traces of Norrin at indicated concentrations binding to and dissociating from Tspan12. ( C ) Steady-state binding curve fit to Norrin-Tspan12 binding (mean ± SD from three independent replicates at each concentration of Norrin) gives a K D of 10.4±1.2 nM (mean ± SEM). ( D ) Observed association rate constant (K obs ), determined from fitting BLI association traces (mean ± SD in three independent experiments), is linearly dependent on Norrin concentration with a slope K on = 0.00019 ± 0.00003 nM –1 s –1 (mean ± SEM). When combined with the K off = 0.0014 ± 0.00016 s –1 (mean ± SEM) determined from fitting the dissociation traces, we obtain a kinetic K D of 7.4±1.4 nM (mean ± SEM). ( E ) BLI traces of the soluble MBP-tagged Tspan12 LEL domain, at the indicated concentrations, associating to and dissociating from a biosensor loaded with MBP-tagged Norrin. Kinetic fitting gives an apparent affinity of 16±3 nM (mean ± SEM). ( F ) BLI traces of 10, 32, or 100 nM Norrin show no binding to a biosensor loaded with a nanodisc-embedded chimeric Tspan12 with the LEL replaced by that of Tspan11. Figure 1—source data 1.
