Gene: Tnni3 (troponin I3, cardiac type) Rattus norvegicus
Symbol: Tnni3
Name: troponin I3, cardiac type
RGD ID: 62052
Description: Predicted to enable several functions, including calcium channel inhibitor activity; calcium-dependent protein binding activity; and cytoskeletal protein binding activity. Involved in cardiac muscle contraction and regulation of smooth muscle contraction. Located in sarcomere. Human ortholog(s) of this gene implicated in intrinsic cardiomyopathy (multiple). Orthologous to human TNNI3 (troponin I3, cardiac type); PARTICIPATES IN acebutolol pharmacodynamics pathway; adrenergic beta receptor agonist and beta-blocker pharmacodynamics pathway; amiodarone pharmacodynamics pathway; INTERACTS WITH (R)-lipoic acid; (R,R)-tramadol; (S)-colchicine.
Type: protein-coding
Previously known as: cardiac troponin I; cTNI; TnI; troponin 1, type 3; Troponin I; troponin I cardiac; troponin I type 3 (cardiac); troponin I, cardiac; troponin I, cardiac muscle
