Calponin is a putative thin filament regulatory protein of smooth muscle that inhibits
actomyosin ATPase in vitro. We have used electron microscopy and three-dimensional …

Calponin is a 33-kDa smooth muscle-specific protein that has been suggested to play a role
in muscle contractility. It has previously been shown to interact with actin, tropomyosin, and …

Calponin, a thin filament-associated protein, inhibits actomyosin adenosinetriphosphatase
in solution and has been suggested to modulate smooth muscle contractility. We used …

Earlier, we proposed that the interaction of gizzard calponin with F-actin, promoting the
inhibition of the actomyosin ATPase activity, involves the NH 2-termi-nal portion of the …

The contribution of electrostatic interactions to the effects of chicken gizzard calponin on the
kinetics of actin polymerization and the bundling of F‐actin were characterized by a …

Cell adhesion and migration are important events that occur during embryonic development,
immune surveillance, wound healing and in tumor metastasis. It is a multi-step process that …

Revised Manuscript Received March 3, 1994· abstract: Calponin inhibits actomyosin Mg2+
ATPase and is proposed to regulate smooth muscle contraction; however, the mechanism …

Calponin is an actin-binding protein known to be a substrate in vitro for several protein
kinases and phosphoprotein phosphatases. We tested the hypothesis that calponin is …

1 Biochemical and quantitative image analysis methods were used to investigate the
anatomical basis for the previously described agonist‐induced redistribution of calponin. 2 …

Cell migration involves the dynamic formation and release of cell-substrate adhesions,
where the exertion and detection of mechanical forces take place. Members of the calpain …
