Research Backgrounds
Troponin I is the inhibitory subunit of troponin, the thin filament regulatory complex which confers calcium-sensitivity to striated muscle actomyosin ATPase activity.
Phosphorylated at Ser-23 and Ser-24 by PRKD1; phosphorylation reduces myofilament calcium sensitivity. Phosphorylated preferentially at Thr-32. Phosphorylation by STK4/MST1 alters its binding affinity to TNNC1 (cardiac Tn-C) and TNNT2 (cardiac Tn-T) (By similarity). Phosphorylated at Ser-43 and Ser-45 by PRKCE; phosphorylation increases myocardium contractile dysfunction.
Interacts with TRIM63 (By similarity). Binds to actin and tropomyosin. Interacts with STK4/MST1 (By similarity).
Belongs to the troponin I family.
