These results demonstrated that most of the HCM-linked cTnI mutations did affect the regulatory processes involving the cTnI molecule, and that at least five mutations (R145G, R145Q, R162W, DeltaK183, K206Q) increased the Ca(2+) sensitivity of cardiac muscle contraction.

To understand the functional consequences of the Lys184 deletion in murine cardiac troponin I (mcTnI(DeltaK184)), we have studied the primary effects of this mutation linked to familial hypertrophic cardiomyopathy (FHC) at the sarcomeric level.

Purified recombinant wild-type cTnI and three of its fHCM-related missense mutants (R145G, G203S and K206Q), alone or in the troponin complex (i.e. together with troponin C and troponin T), in the non-phosphorylated or protein kinase A-bisphosphorylated forms were proteolyzed in vitro in the presence of Calpain-1 (0.05-2.5 U) at 30 degrees C. Following incubation with Calpain-1 for 0.5, 30, 60 or 120 min, the extent of protein degradation was evaluated through the use of Western immunoblotting and densitometry.

Thus, these two fHCM-linked cTnI mutations, although reflecting similar pathological situations, exert different effects on the actomyosin system per se and in response to bis-phosphorylation of cTnI.
