Filamins are multi-domain, actin cross-linking, and scaffolding proteins. In addition to the actin cross-linking function,
filamins have a role in mechanosensor signaling. The mechanosensor function is mediated by domain-domain interaction in
the C-terminal region of filamins. Recently, we have shown that there is a three-domain interaction module in the Nterminal
region of filamins, where the neighboring domains stabilize the structure of the middle domain and thereby
regulate its interaction with ligands. In this study, we have used small-angle X-ray scattering as a tool to screen for potential
domain-domain interactions in the N-terminal region. We found evidence of four domain-domain interactions with varying
flexibility. These results confirm our previous study showing that domains 3, 4, and 5 exist as a compact three domain
module. In addition, we report interactions between domains 11–12 and 14–15, which are thus new candidate sites for
mechanical regulation.
