titin-telethonin complex
A protein complex formed between the N-terminus of the giant sarcomeric filament protein titin and the Z-disk ligand, telethonin. The complex is part of the Z-disk of the skeletal and cardiac sarcomere. Telethonin binding to titin might be essential for the initial assembly, stabilization and functional integrity of the titin filament, and hence important for muscle contraction relaxation in mature myofibrils.
