Troponin I, cardiac muscle is a protein that in humans is encoded by the TNNI3 gene.[1][2] It is a tissue-specific subtype of troponin I, which in turn is a part of the troponin complex.

Interactions[edit]

TNNI3 has been shown to interact with PKD2L1,[3] Troponin C type 1[4][5][6][7][8] and Polycystic kidney disease 2.[9]
