Example sentences for: actin

How can you use “actin” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • From the thicker smooth muscle layer of mesenteric artery we obtained a greater amount of total protein than from the thinner veins, but the fraction of the major motor proteins actin and myosin, as well as of thin filament-binding protein calponin, was indistinguishable.

  • This would increase the probability of cross-bridge binding to actin, resulting in a greater number of cross-bridges exerting force during the twitch contraction.

  • When the myosin activity was blocked with BDM treatment, continued actin polymerization, thought to occur as elongation of existing filaments, lead to protrusion [ 12 27 28 ] . Our observation of BDM activity suggests an alternative explanation.

  • These studies indicate that actin and the microtubule cytoskeleton play a pivotal role in cell expansion and branching during trichome development [ 32].

  • Cyclic nucleotide induced relaxation is associated with phosphorylation of heat shock protein 20 (also known as HSP20 or P20) on serine 16 [ 10 11 12 ] . More recently, ser 16-HSP20 phosphorylation was shown to specifically and temporally correlate with "force suppression" rather than the "deactivation" form of relaxation [ 8 10 ] . A region of HSP20 (residues 110-121) has sequence homology with troponin I; peptides from this region bound thin filaments, reduced actin activated myosin S1 ATPase activity, and relaxed skinned swine carotid artery [ 10 ] . We hypothesized that binding of ser 16-phosphorylated HSP20 to the thin filament may "turn off" thin filaments so that phosphorylated myosin does not interact with the thin filament (i.e.
