CC   -!- FUNCTION: Troponin I is the inhibitory subunit of troponin, the thin
CC       filament regulatory complex which confers calcium-sensitivity to
CC       striated muscle actomyosin ATPase activity.
CC       {ECO:0000256|ARBA:ARBA00001988}.
CC   -!- SUBUNIT: Binds to actin and tropomyosin.
CC       {ECO:0000256|ARBA:ARBA00038767}.
CC   -!- SIMILARITY: Belongs to the troponin I family.
CC       {ECO:0000256|ARBA:ARBA00009930}.
