Mapping the actin filament with myosin.
Structural studies have shown that the heads of the myosin motor molecule bind preferentially to "target zones" of favorably oriented sites on the helices of the actin filament. We present direct evidence for target zones from the interactions of a single myosin head with an actin filament held between two optically trapped beads. With compliant traps, thermal motions of the filament allow the ...
متن کاملA consistent picture of the actin filament related to the orientation of the actin molecule
We show that freeze-dried actin filaments which have been rotary shadowed with a light coat of platinum appear very similar in morphology and width to negatively-stained filaments. The addition of a thicker coat of platinum to such preparations gives the actin filaments a different morphology and width, which are similar to those of the rotary-shadowed, quick-frozen filaments described by Heuse...
متن کاملA single-headed fission yeast myosin V transports actin in a tropomyosin-dependent manner
Myo51, a class V myosin in fission yeast, localizes to and assists in the assembly of the contractile ring, a conserved eukaryotic actomyosin structure that facilitates cytokinesis. Rng8 and Rng9 are binding partners that dictate the cellular localization and function of Myo51. Myo51 was expressed in insect cells in the presence or absence of Rng8/9. Surprisingly, electron microscopy of negativ...
متن کاملSingle turnovers of fluorescent ATP bound to bipolar myosin filament during actin filaments sliding
The nucleotide turnover rates of bipolar myosin thick filament along which actin filament slides were measured by the displacement of prebound fluorescent ATP analog 2'(3')-O-[N-[2-[(Cy3)]amindo]ethyl] carbamoyl]-adenosine 5' triphosphate (Cy3-EDA-ATP) upon flash photolysis of caged ATP. The fluorescence of the thick filament where actin filament slides decayed with two exponential processes. T...
متن کاملArchitecture Dependence of Actin Filament Network Disassembly
Turnover of actin networks in cells requires the fast disassembly of aging actin structures. While ADF/cofilin and Aip1 have been identified as central players, how their activities are modulated by the architecture of the networks remains unknown. Using our ability to reconstitute a diverse array of cellular actin organizations, we found that ADF/cofilin binding and ADF/cofilin-mediated disass...
