A Western blot of representative B16F1-mS1 and FurKO#2-ctrl or -βA cell SNs, and ImageJ quantification of the proportions of mature, hemicleaved, and uncleaved Activin-A in independent sample preparations from the indicated cell lines used as inputs to test Activin-A binding to immobilized ActRIIB-Fc by plasmon resonance measurements. The microfluidic chamber used to inject cell SNs on a nanoplasmonic <t>chip</t> <t>functionalized</t> with ActRIIB-Fc on gold nanoparticles is depicted on the right. Drops in signal intensity are induced by Activin-A binding to ActRIIB-Fc. B Binding of the different forms of Activin-A was evaluated by injecting the B16F1-βA or FurKO#2-βA cell SNs analyzed in ( A ). B16F1-mS1, or B16F1-Ctrl cells expressing empty lentivirus served as specificity controls. Error bars, SEM ( n = 3 independent experiments); * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001, Student’s t -test. C Schematic of the conversion of hemicleaved Activin-A (A70) to A60 by furin cleavage of the second βA subunit, and strategy to monitor the cleavage using anti-Flag and anti-Activin-A (ActA) antibodies. In this model, an allosteric cystine bond (S–S) links the prodomain (violet) of one βA subunit to the C-terminal region (yellow) in A70 and A60. Prodomain that is not covalently attached (light shading) can be displaced by cognate type II receptors.
