abstract = {Active muscles generate substantial mechanical forces by
the contraction/relaxation cycle, and, to maintain an
ordered state, they require molecular structures of
extraordinary stability. These forces are sensed and
buffered by unusually long and elastic filament proteins
with highly repetitive domain arrays. Members of the
myomesin protein family function as molecular bridges that
connect major filament systems in the central M-band of
muscle sarcomeres, which is a central locus of passive
stress sensing. To unravel the mechanism of molecular
elasticity in such filament-connecting proteins, we have
determined the overall architecture of the complete
C-terminal immunoglobulin domain array of myomesin by X-ray
crystallography, electron microscopy, solution X-ray
scattering, and atomic force microscopy. Our data reveal a
dimeric tail-to-tail filament structure of about 360 Å in
length, which is folded into an irregular superhelical coil
arrangement of almost identical α-helix/domain modules. The
myomesin filament can be stretched to about 2.5-fold its
original length by reversible unfolding of these linkers, a
mechanism that to our knowledge has not been observed
previously. Our data explain how myomesin could act as a
highly elastic ribbon to maintain the overall structural
organization of the sarcomeric M-band. In general terms, our
data demonstrate how repetitive domain modules such as those
found in myomesin could generate highly elastic protein
structures in highly organized cell systems such as muscle
sarcomeres.},
