Tnnt3 Gene Summary [Mouse]
Predicted to enable calcium-dependent protein binding activity and cytoskeletal protein binding activity. Predicted to contribute to actin binding activity. Predicted to be involved in several processes, including positive regulation of calcium-dependent ATPase activity; sarcomere organization; and skeletal muscle contraction. Predicted to be part of troponin complex. Is expressed in several structures, including diaphragm; heart; lower jaw; musculature; and urinary system. Human ortholog(s) of this gene implicated in distal arthrogryposis type 2B and distal arthrogryposis type 2B2. Orthologous to human TNNT3 (troponin T3, fast skeletal type).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Tnnt3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
