α-Calponin is a thin-filament-associated protein which has been implicated in the regulation
of smooth muscle contraction. Quantification of the tissue content of rat tail arterial smooth …

Calponin, an actin-and Ca (2+)-calmodulin-binding protein characterized as an inhibitory
factor of the smooth-muscle actomyosin activity, has also been shown to be present in some …

Background Calponin is a calmodulin‐and actin‐binding protein expressed in smooth
muscle. It promotes actin polymerization and inhibits actin‐activated myosin ATPase activity …

Acidic calponin, an F‐actin‐binding protein, is particularly enriched in brain, where calponin
protein and mRNA are mainly expressed by neurons. The presence of calponin …

Calponin-h1 is a 34-kDa myofibrillar thin filament, actin-binding protein that is expressed
exclusively in smooth muscle cells (SMCs) in adult animals. To examine the molecular …

Calponin is a basic smooth‐muscle‐specific protein capable of binding to F‐actin,
tropomyosin and calmodulin in vitro. Using two‐dimensional gel electrophoresis, we show …

Calponin has been implicated in the regulation of smooth muscle contraction through its
interaction with F-actin and inhibition of the actin-activated MgATPase activity of …

Revised Manuscript Received March 22, 1995® abstract: Calponin is a smooth muscle-
specific, thin filament-associated protein which has been implicated in the regulation of …

Calponin from chicken gizzard induced polymerization of actin in the presence of 10 mM
KCl. Only 2 min after the addition of KCl in the presence of a 0.0625-0.25: 1 molar ratio of …

Many actin-binding proteins contain calponin homology (CH) domains, but the manner in
which these domains interact with F-actin has been controversial. Crystal structures have …
