my·o·sin

 (mī′ə-sĭn)
n.
Any of a class of proteins that bind with actin filaments and generate many kinds of cell movement, especially the contraction of myofibrils in muscle cells.

[Greek muos, genitive of mūs, muscle; see myo- + -in.]

myosin

(ˈmaɪəsɪn)
n
(Biochemistry) the chief protein of muscle that interacts with actin to form actomyosin during muscle contraction; it is also present in many other cell types

In preclinical studies, MYK-224 was shown to attenuate hyperactive myosin proteins containing known pathogenic HCM mutations.
This creates force differences along different regions of the cortex, and the resulting cortical flow transports myosins and other polarity proteins to the front of the zygote, thereby creating front-rear asymmetry.
According to our previous studies [5,12], the major factors leading to PSE-like meat having poor protein functionalities are concluded as protein conformation, characteristic of salt soluble proteins, myosin and actin denaturation during meat processing, which also depend on pH and ionic strength conditions.
The eLife study looked at a mutation in myosin known as K146N (the mutation name is derived from the name of the affected amino acid residue and how it is altered in myosin).
In the first phase of ontogenesis, the level of myosin in piglets intact platelets was also low, accounting for 10.9 [+ or -] 0.09% of the total protein content in the platelet, reaching 18.3[+ or -]0.09% of the total protein content of the platelet by 12 months.
More than 80 MYO7A mutations have been identified and are known to inherit in a recessive manner.11 This gene encode protein, the myosin VIIA, expressed in inner ear, retina, testis and lungs.
We observed that all embryos exposed to mercuric chloride showed little to no positive immunohistochemical staining for myosin (Fig.
This was unexpected, because myosin was not known to be involved in PKD.
Because of lacking cardio specificity, we abandoned the myosin light chain work and in 1989 finally published our work on the assay development for cardiac troponin T (cTnT) jointly with Boehringer Mannheim (3).
In meat samples, the main protein bands identified in the range of molecular weights from 250 to 10kDa were myosin heavy chain (MHC), [alpha]-actinin ([alpha]-act), desmin, actin (ACT), troponin T (TnT), tropomyosin (TPM), myosin light chains 1 (MLC1), troponin C (TnC), and myosin light chains 2 (MLC2).
Phosphorylation by ROCK inactivates a myosin phosphatase, retaining myosin II in the phosphorylated or active state [34, 35].
