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
