Function

[CNN1_CHICK] Thin filament-associated protein that is implicated in the regulation and modulation of smooth muscle contraction. It is capable of binding to actin, calmodulin, troponin C and tropomyosin. The interaction of calponin with actin inhibits the actomyosin Mg-ATPase activity.

Publication Abstract from PubMed

Calponin is involved in the regulation of contractility and organization of the actin cytoskeleton in smooth muscle cells. It is the archetypal member of the calponin homology (CH) domain family of actin binding proteins that includes cytoskeletal linkers such as alpha-actinin, spectrin, and dystrophin, and regulatory proteins including VAV, IQGAP, and calponin. We have determined the first structure of a CH domain from a single CH domain-containing protein, that of calponin, and have fitted the NMR-derived coordinates to the 3D-helical reconstruction of the F-actin:calponin complex using cryo-electron microscopy. The tertiary fold of this single CH domain is typical of, yet significantly different from, those of the CH domains that occur in tandem pairs to form high-affinity ABDs in other proteins. We thus provide a structural insight into the mode of interaction between F-actin and CH domain-containing proteins.
