Classified under:

Nouns denoting substances

Hypernyms ("myosin" is a kind of...):

Holonyms ("myosin" is a substance of...):

actomyosin (a protein complex in muscle fibers; composed of myosin and actin; shortens when stimulated and causes muscle contractions)

 Context examples 

This protein plays a role in both myosin phosphorylation and smooth muscle cell contraction.

(Myosin Light Chain Kinase, Smooth Muscle, NCI Thesaurus)

NO activates guanylyl cyclase, thereby increasing the synthesis of cGMP within smooth muscle, resulting in dephosphorylation of light chain myosin and relaxation of peripheral arteries and veins.

(Isosorbide Dinitrate, NCI Thesaurus)

In turn, free Ca+ triggers dephosphorylation of light chain myosin and relaxation of peripheral arteries and veins.

(Isosorbide, NCI Thesaurus)

The phosphorylation of myosin affects its role in smooth muscle contraction, platelet formation, and possibly other processes.

(Myosin Phosphatase Pathway, NCI Thesaurus/BIOCARTA)

Movement is driven by actin—a major component of the cell’s skeleton, or cytoskeleton—and the molecular motor myosin.

(New Mechanism of Cell Movement Revealed, NIH)

This allele, which encodes myosin-2 protein, plays a role in muscle contraction.

(MYH2 wt Allele, NCI Thesaurus)

This allele, which encodes myosin-1 protein, is involved in the contraction of skeletal muscles.

(MYH1 wt Allele, NCI Thesaurus)

The determination of the amount of myosin light chain 3 present in a sample.

(Myosin Light Chain 3 Measurement, NCI Thesaurus)

A measurement of myosin light chain 3 in a biological specimen.

(Myosin Light Chain 3 Measurement, NCI Thesaurus/CDISC)

Myosin-1 (1939 aa, ~223 kDa) is encoded by the human MYH1 gene.

(Myosin-1, NCI Thesaurus)
