FAMILY
  • troponin I family
  • CATEGORY motor/contractile , regulatory , structural protein
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm,cytoskeleton
    basic FUNCTION
  • preventing actin and myosin interaction in resting muscle tissue
  • involved in the regulation of muscle contraction
  • may be playing a role in regulation of smooth muscle function
  • playing potentially a role in regulation of smooth muscle function
  • inhibitory subunit of the troponin complex in the sarcomeric thin filament of striated muscle and plays a central role in the calcium regulation of contraction and relaxation
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • inhibitory subunit of troponin
  • Troponin consists of three subunits: an inhibitory subunit TNNI2, a Ca2+-binding subunit TNNC2, and TNNT2
