Calponin is a calcium binding protein. Calponin tonically inhibits the ATPase activity of myosin in smooth muscle. Phosphorylation of calponin by a protein kinase, which is dependent upon calcium binding to calmodulin, releases the calponin`s inhibition of the smooth muscle ATPase. == Structure and function == Calponin is mainly made up of α-hel....

<protein> Calcium and calmodulin binding troponin T like protein (34 kD) isolated from chicken gizzard and bovine aortic smooth muscle. Interacts with F actin and tropomyosin in a calcium sensitive manner and acts as a regulator of smooth muscle contraction (inhibits when not phosphorylated). Distinct from caldesmon and myosin light chain kin...

Calcium and calmodulin binding troponin T-like protein (34 kD) isolated from chicken gizzard and bovine aortic smooth muscle. Interacts with F-actin and tropomyosin in a calcium sensitive manner and acts as a regulator of smooth muscle contraction (inhibits when not phosphorylated). Distinct from caldesmon and myosin light chain kinase, but has some antigenic cross-reactivity with cardiac Troponin-T.
