The residues in cardiac TnT with phosphorylation regulations are summarized. The residue numbers for phosphorylatable serine and threonine are that in human cardiac TnT with the first methionine included. The phosphorylation of cardiac TnT at these residues is compared with the counterparts in fast TnT and slow TnT. C, conserved; N, non-conserved. Kinases responsible for each phosphorylation, functional effects, and references are also listed. Mutations in cardiomyopathies Point mutations in TNNT2 gene cause various types of cardiomyopathies, including hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM) and restrictive cardiomyopathy (RCM). The table below summarizes representative TNNT2 mutations and abnormal splicings found in human and animal cardiomyopathies. Amino Acid residues of mutations were numbered as in human cardiac TnT with the first methionine included. Mutations of cardiac TnT that caused cardiomyopathies were mostly found in the conserved middle and C-terminal regions.
