| Gene Symbol | TNNI3 |
| Gene Full Name | troponin I, cardiac 3 |
| Background | Troponin I (TnI) is 1 of 3 subunits, along with troponin C (TnC) and Troponin T (TnT) of troponin complex found in cardiac (cTnI) and fast skeletal (fsTnI) muscle (Noland et al, 1995). Protein kinase C-mediated phosphorylation of cardiac myofilament proteins has been shown to depress the actomyosin interaction and may be important during heart failure. (Montgomery et al, 2002) Studies indicate that phosphorylation of Ser43 and Ser45 of cardiac troponin I plays a substantial role in the PKCmediated depression. (Montgomery et al, 2002). |
| Research Area | Cell Biology and Cellular Response antibody; Controls and Markers antibody; Developmental Biology antibody; Signaling Transduction antibody |
| Calculated MW | 24 kDa |
| PTM | Phosphorylated at Ser-42 and Ser-44 by PRKCE; phosphorylation increases myocardium contractile dysfunction (By similarity). Phosphorylated at Ser-23 and Ser-24 by PRKD1; phosphorylation reduces myofilament calcium sensitivity. Phosphorylated preferentially at Thr-31. Phosphorylation by STK4/MST1 alters its binding affinity to TNNC1 (cardiac Tn-C) and TNNT2 (cardiac Tn-T). |
