Protocol Available protocols: Western Blotting Specificity / Sensitivity Troponin I (D6F8) Rabbit Monoclonal Antibody recognizes endogenous levels of total troponin I protein. Species Reactivity: Human, Mouse, Rat Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human troponin I protein. Background Troponin, working in conjunction with tropomyosin, functions as a molecular switch that regulates muscle contraction in response to changes in the intracellular Ca concentration. Troponin consists of three subunits: the Ca -binding subunit troponin C (TnC), the tropomyosin-binding subunit troponin T (TnT), and the inhibitory subunit troponin I (TnI) (1). In response to β-adrenergic stimulation of the heart, Ser23 and Ser24 of TnI (cardiac) are phosphorylated by PKA and PKC. This phosphorylation stimulates a conformational change of the regulatory domain of TnC, reduces the association between TnI and TnC, and decreases myofilament Ca sensitivity by reducing the Ca binding affinity of TnC (1-3).
