Figure 6. ADAMTS17-PCD binds to fibrillin-2 but not fibrillin-1 or fibronectin.

Figure 6

(a) Domain structure of recombinant fibrillin-1 and fibrillin-2 peptides used to analyze interactions with ADAMTS17-PCD (PCD) or ADAMTS17-AD (AD). (b) Coomassie blue stained SDS-PAGE showing the integrity and purity of the recombinant proteins used in the interaction studies. The asterisks indicate the full-length constructs. M, mature enzyme; Z, zymogen. (c) Surface plasmon resonance shows binding of FBN2-N and FBN2-C to ADAMTS17-PCD (left-hand panels) or ADAMTS17-AD (right-hand panels). Binding was dose-dependent and Ca2+-dependent. The dissociation constant (KD) was calculated assuming 1:1 stoichiometry. (d) ADAMTS17-PCD (top panel) or ADAMTS17-AD (bottom panel) did not bind to FBN1-N, FBN1-C, or cellular fibronectin (FN) analytes and ADAMTS17-AD did not self-interact or bind to ADAMTS17-PCD.
