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.
