Calponin is an extensively studied actin-binding protein, but its function is not well
understood. Among three isoforms of calponin, h2-calponin is found in both smooth muscle …

h2-Calponin is found in both smooth muscle and nonmuscle cells, and its function remains
to be established. Western blots with specific monoclonal antibodies detected significant …

Calponin is an actin filament-associated protein and its h2 isoform inhibits cell motility. Here
we report significant expression of h2-calponin in prostate epithelial cells, which is …

Calponins have been implicated in the regulation of actomyosin interactions in smooth
muscle cells, cytoskeletal organisation in nonmuscle cells, and the control of neurite …

Three homologous calponin isoforms, named h1, h2, and acidic calponins, have been found
in birds and mammals. Based primarily on studies of chicken gizzard smooth muscle (h1) …

Calponin is an actin filament-associated regulatory protein expressed in smooth muscle and
non-muscle cells. Calponin is an inhibitor of the actin-activated myosin ATPase. Three …

Background: The actin-binding site of several cytoskeletal proteins is comprised of two
calponin homology (CH) domains in a tandem arrangement. As a single copy, the CH …

Calponin (h1 isoform) was characterized as a smooth muscle specific, actin-, tropomyosin-,
calmodulin-binding protein and described as a factor which inhibits contraction. H2 …

Calponin is a thin filament-associated smooth muscle protein that has been suggested to
play a role in the regulation of smooth muscle contraction. We have used circular dichroism …

The purpose of this study was to address the paradox of calponin localization with α-actinin
and filamin, two proteins with tandem calponin homology (CH) domains, by determining the …
