Troponin T

Troponin T is a part of the troponin complex. It binds to tropomyosin, interlocking them to form a troponin-tropomyosin complex.

The tissue specific subtypes are:

v • d • e

Histology: muscle tissue

skeletal muscle/general

epimysium, fascicle, perimysium, endomysium, muscle fiber (intrafusal, extrafusal), myofibril

sarcomere (a, i, and h bands; z and m lines), myofilaments (thin filament/actin, thick filament/myosin, elastic filament/titin, nebulin), tropomyosin, troponin (T, C, I)

costamere (dystrophin, α,β-dystrobrevin, syncoilin, synemin/desmuslin, dysbindin, sarcoglycan, dystroglycan, sarcospan), desmin

neuromuscular junction, motor unit, muscle spindle, excitation-contraction coupling, sliding filament mechanism

myoblast, satellite cell, sarcoplasm, sarcolemma, sarcoplasmic reticulum, T-tubule

cardiac muscle

myocardium, intercalated disc, nebulette

smooth muscle

calmodulin, vascular smooth muscle
