Background Information
Troponin I (TnI) is the inhibitory subunit of troponin; the thin filament regulatory complex that confers calcium sensitivity to striated muscle actomyosin ATPase activity. Cardiac Troponin I (cTnI) is encoded by the TNNI3 gene located on chromosome 19 in humans.
What is the molecular weight of cTnI?
The molecular weight of cTnI is 24 kDa.
What is the tissue specificity of cTnI?
cTnI is produced exclusively by cardiac muscle.
What are the post-translational modifications of cTnI?
cTnI at Ser-23 and Ser-24 under adrenergic stimulation enhances the relaxation of cardiac muscle.
What is the role of cTnI in disease?
cTnI is considered to be one of the most specific and sensitive markers of myocardial damage such as acute myocardial infarction (AMI), as detection of cTnI in serum is widely accepted as a diagnostic tool (PMID: 15452154). Defects in TNNI3 lead to cardiomyopathy familial hypertrophic type 7 (CMH7); an inherited heart disorder characterized by ventricular hypertrophy (PMID: 8205619). Defects in TNNI3 can also cause cardiomyopathy familial restrictive type I (RCM1) (PMID: 20617149) and cardiomyopathy dilated type 2A (CMD2A) (PMID: 12531876). These disorders are characterized by the impaired filling of ventricles or ventricular dilation respectively.
