Antigen/Purification: ExpandCollapse

The antigen is a phosphopeptide corresponding to amino acid residues surrounding the phospho Ser150 of mouse troponin I, cardiac (cTnI).

The antibody is prepared from pooled rabbit serum by affinity purification via sequential chromatography on phospho- and dephospho-peptide affinity columns.

Biological Significance: ExpandCollapse

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. cTnI is phosphorylated by protein kinase C and protein kinase A at Ser23/24 (Noland et al, 1995) and is phosphorylated by AMPK at Ser23 and Ser150 (Solis et al, 2011). Evidence suggests that AMPK, a critical regulator of cardiac energetics, prefers phosphorylating Ser150 over Ser23, and may play a role in regulating energy consumption through altering the phosphorylation status of cTnI (Solis et al., 2011).

Troponin I, cardiac Ser150 Antibody
Western blot of mouse heart lysate showing specific immunolabeling of ~25 kDa cardiac troponin I protein phosphorylated at Ser150 in the first lane (-). Phosphospecificity is shown in the second lane (+) where the immunolabeling is completely greatly decreased by blot treatment with lambda phosphatase (λ-Ptase, 1200 units for 30 minutes).
