Summary

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 PKC-mediated depression. (Montgomery et al, 2002).

Storage & Stability

Images

Western blot of mouse heart lysate showing specific immunolabeling of the ~25k cTnI protein phosphorylated at Ser43 (control). Phosphospecificity is shown in the second lane (lambda-phosphatase: λ-Ptase). The blot is identical to the control except that the lysate was incubated in λ-Ptase (1400 units for 30 min). The immunolabeling is greatly decreased by treatment with λ-Ptase.
