The actin cytoskeleton plays a major role in cell motility that is essential for the function of
phagocytes. Calponin is an actin-associated regulatory protein. Here we report the finding of …

We cloned and sequenced cDNAs encoding calponin (Calp) and SM22 (smooth muscle-
specific 22-kDa protein) from rat aorta (RaA) smooth muscle (Smu) cells. The 1504-bp calp …

The roles of calponin and caldesmon and their interaction in regulation of smooth muscle
contraction are controversial. Recently, strong binding between these two proteins has been …

Defining regulatory elements governing cell-restricted gene expression can be difficult
because cis-elements may reside tens of kilobases away from start site (s) of transcription …

Calponin inhibits actin-activated myosin adenosinetriphosphatase (ATPase) activity, and
phosphorylation reverses this inhibition. Calponin phosphorylation has been demonstrated …

Calponin phosphorylation was quantitated in 32 P-labeled porcine arterial, uterine, tracheal,
stomach and bladder smooth muscles. The negligible amount of 0.003–0.008 mol [32 P] …

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

Calponin is an actin filament-associated regulatory protein, and its h2 isoform is expressed
in lung alveolar epithelial cells under postnatal upregulation during lung development …

Native calponin is able to bind 2 mol of calcium binding protein (CaBP) per mole calponin.
This study extends this observation to define the 2 domains of interaction, one of which is …

Polyclonal antibody against phosphorylated calponin was raised in rabbits by application of
the peptide corresponding to residues 183-195 of calponin phosphorylated by protein …
