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) …

Smooth muscle contraction is regulated primarily by the reversible phosphorylation of
myosin II (Somlyo & Somlyo, 1994), but may also be modulated by a thin filamentassociated …

Calponin is a smooth muscle specific, actin-, tropomyosin-and calmodulin-binding protein
thought to be involved in some way in the regulation or modulation of contraction. Here we …

Calponin is a thin filament-associated protein that is implicated in the regulation and
maintenance of smooth muscle contraction. Molecular cloning of chicken gizzard calponin …

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

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 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 …

Previously, we attributed the binding of F-actin to the 38-residue stretch of gizzard calponin
encompassing the sequence A145− Y182 and postulated the hexapeptide motif VKYAEK …

Two‐dimensional gel analysis of basic proteins in developing human smooth muscle
identifies calponin as a prominent marker of the differentiated phenotype. Adult tissue …

Calponin is a thin filament associated protein found in smooth muscle as a potential
modulator of contraction. Five mouse monoclonal antibodies (mAbs CP1, CP3, CP4, CP7 …
