Example Sentences:
(1) The pathology resulting from a missense mutation at residue 403 further suggests that a critical function of myosin is disrupted by this mutation.
(2) The combined amounts of S-1 and Fab binding to actin suggested that the activation of the myosin ATPase activity was due to actin free of Fab.
(3) Variations in light chain composition, particularly fast and slow myosin light chain 1, appeared to occur independently of the variations in heavy chain composition, suggesting that some myosin molecules consist of mixtures of slow- and fast-type subunits.
(4) Normal rat soleus myosin has a major slow and a minor fast component due to two populations of muscle fibers.
(5) By applying this method to rat cardiac whole muscle, high-molecular weight proteins, such as myosin heavy chains, are focused on the first-dimensional gels and, in addition, minor components are resolved on the second-dimensional gels, without loss during equilibration with detergent.
(6) Based on incorporation of radioactively labeled N-ethylmaleimide, the readily reactive thiol groups of isolated myosin (EC 3.6.1.3) from fast, slow and cardiac muscles could be classified into 3 types.
(7) To identify cells of different myogenic lineages, myotubes were analyzed for content of fast and slow classes of myosin heavy chain (MHC) isoforms by immunocytochemistry and immunoblotting using specific monoclonal antibodies.
(8) We have determined by protein chemistry methods the amino acid sequence of light chain 2 from Acanthamoeba castellanii myosin-II (ALC2).
(9) Chloride caused a significant concentration-dependent shortening of myosin rods due to destabilization of the alpha-helical double coiled rod structure.
(10) These force-generators are identified with projections (cross-bridges) on the thick filament, each consisting of part of a myosin molecule.
(11) The myogenic potential of chick limb mesenchyme from stages 18-25 was assessed by micromass culture under conditions conductive to myogenesis, and was measured as the proportion of differentiated (muscle myosin-positive) mononucleated cells detected.
(12) In smooth muscles there is no organized sarcomere structure wherein the relative movement of myosin filaments and actin filaments has been documented during contraction.
(13) When approximately 80% of the myosin light chain was thiophosphorylated, the nucleoside diphosphate exchange occurred at a much faster rate and was almost complete in 2 min.
(14) One of the atrial myosins is immunologically close to the ventricular myosin, but they each differ with respect to their heavy chains, light chains, and enzymatic activities.
(15) The images of 56 tubular myosin filaments of the fleshfly and 62 filaments of the housefly were digitized and computer processed by rotational averaging.
(16) The ninaC gene encodes two retinal specific proteins (p132 and p174) consisting of a protein kinase domain joined to a domain homologous to the head region of the myosin heavy chain.
(17) These antibodies were used to study the localization and synthesis of myosin heavy chain and tropomyosin in the limb buds of premetamorphic (stage VI-VII) tadpoles treated with triiodothyronine (T3) to induce metamorphosis.
(18) Of 72 sera from patients with MC or DCM 45 (62.5%) bound to the peptides derived from ANT, 32 (44.4%) reacted with the sequences from myosin, in contrast to healthy controls.
(19) Specific myosin polypeptides have been identified by immunoprecipitation with an antibody made to purified adult chicken skeletal muscle myosin.
