 complex. It binds to tropomyosin

Tropomyosin

Tropomyosin is an actin-binding protein that regulates actin mechanics. It is important, among other things, for muscle contraction. Tropomyosin, along with the troponin complex, associate with actin in muscle fibers and regulate muscle contraction by regulating the binding of myosin...

, interlocking them to form a troponin-tropomyosin complex.

The tissue specific subtypes are:

• Slow skeletal troponin T1, TNNT1
  TNNT1
  Troponin T, slow skeletal muscle is a protein that in humans is encoded by the TNNT1 gene.-External links:* -Further reading:...

• Cardiac troponin T2, TNNT2
  TNNT2
  Troponin T type 2 , also known as TNNT2, is a protein which in humans is encoded by the TNNT2 gene.The protein encoded by this gene is the tropomyosin-binding subunit of the troponin complex, which is located on the thin filament of striated muscles and regulates muscle contraction in response to...

• Fast skeletal troponin T3, TNNT3
  TNNT3

Troponin T binds to tropomyosin and helps position it on actin . And in a less complicated light, Troponin T modulates contraction of striated muscle

Troponin T was discovered by the German
