Caltropin caldesmon

Caltropin, which is modulated by Ca2+, binds to CaD in a Ca2+-dependent manner with high affinity. It is also very potent in regulating caldesmon s inhibition in a calcium-dependent manner and could conceivably be the Ca + factor that regulates CaD in smooth muscle. [Pg.112]

FIGURE 9 A troponinlike model for cooperative caldesmon regulation of the thin filament caldesmon (CaD), tropomyosin (TM), actin (A), and myosin (M). Domain 1 corresponds to the N-terminal region of caldesmon domains 3 and 4b represent C-terminal amino acid residues from 508 to 565 and from 658 to 756, respectively. Caltropin (CaT).
