Unc45b forms a cytosolic complex with Hsp90 and targets the unfolded myosin motor domain. [PDF]
PLoS ONE, 2008 Myosin folding and assembly in striated muscle is mediated by the general chaperones Hsc70 and Hsp90 and a myosin specific co-chaperone, UNC45. Two UNC45 genes are found in vertebrates, including a striated muscle specific form, Unc45b.

Internal Motility in Stiffening Actin-Myosin Networks [PDF]
Phys. Rev. Lett. 93, 268101 (2004), 2003 We present a study on filamentous actin solutions containing heavy meromyosin subfragments of myosin II motor molecules. We focus on the viscoelastic phase behavior and internal dynamics of such networks during ATP depletion. Upon simultaneously using micro-rheology and fluorescence microscopy as complementary experimental tools, we find a sol-gel ...

Protease-sensitive regions in myosin subfragment 1. [PDF]
Proceedings of the National Academy of Sciences, 1983 Proteolytic digestions of myosin subfragment 1 (S-1) with elastase, subtilisin, papain, thermolysin, and Staphylococcus aureus protease reveal that the two trypsin-sensitive regions in S-1 have broad protease susceptibility. The cleavage of S-1 by these enzymes yields products that correspond within 1-2 kilodaltons (kDa) to the 25-, 50-, and 20-kDa ...

Flexibility of myosin rod, light meromyosin, and myosin subfragment-2 in solution. [PDF]
Proceedings of the National Academy of Sciences, 1977 Myosin rod was prepared by papain proteolysis of myosin. The components of rod, light meromyosin (LMM) and subfragment-2 (S-2), were prepared by proteolysis of myosin and rod, respectively, using trypsin treated with tosylphenylalanine chloromethyl ketone.

Polymerization of G-actin by myosin subfragment 1.
Journal of Biological Chemistry, 1988 The polymerization of actin from rabbit skeletal muscle by myosin subfragment 1 (S-1) from the same source was studied in the depolymerizing G-actin buffer. The polymerization reactions were monitored in light-scattering experiments over a wide range of actin/S-1 molar rations.

Model for processive movement of myosin V and myosin VI [PDF]
Chinese Physics, Vol.14, No.4 (2005) 744-752, 2003 Myosin V and myosin VI are two classes of two-headed molecular motors of the myosin superfamily that move processively along helical actin filaments in opposite directions. Here we present a hand-over-hand model for their processive movements. In the model, the moving direction of a dimeric molecular motor is automatically determined by the relative ...

Characterization of a caldesmon fragment that competes with myosin-ATP binding to actin. [PDF]
, 1993 The protein caldesmon inhibits actin-activated ATP hydrolysis of myosin and inhibits the binding of myosin*ATP to actin. Afragment isolated from a chymotryptic digest of caldesmon contains features of the intact molecule that make it useful as a ...

Cytotoxic mAb from Rheumatic Carditis Recognizes Heart Valves and Laminin [PDF]
, 2000 Anti-streptococcal antibodies cross-reactive with N-acetyl-bD-glucosamine (GlcNAc) and myosin are present in the sera of patients with rheumatic fever (RF). However, their role in tissue injury is not clear.
