abstract = {The integrity of living tissues is maintained by adhesion
domains of trans-bonds formed between cadherin proteins
residing on opposing membranes of neighbouring cells. These
domains are stabilized by lateral cis-interactions between
the cadherins on the same cell. However, the origin of
cis-interactions remains perplexing since they are detected
only in the context of trans-bonds. By combining
experimental, analytical and computational approaches, we
identify bending fluctuations of membranes as a source of
long-range cis-interactions, and a regulator of
trans-interactions. Specifically, nanometric membrane
bending and fluctuations introduce cooperative effects that
modulate the affinity and binding/unbinding rates for
trans-dimerization, dramatically affecting the nucleation
and growth of adhesion domains. Importantly, this regulation
relies on physical principles and not on details of
protein–protein interactions. These omnipresent
fluctuations can thus act as a generic control mechanism in
all types of cell adhesion, suggesting a hitherto unknown
physiological role for recently identified active
fluctuations of cellular membranes.},
