CMD1FFCMD2ACMH7RCM1TNNC1cTnI
Chromosome 19
Chromosome location 19q13.42
Summary Troponin I (TnI), along with troponin T (TnT) and troponin C (TnC), is one of 3 subunits that form the troponin complex of the thin filaments of striated muscle. TnI is the inhibitory subunit; blocking actin-myosin interactions and thereby mediating stria
