Abstract
The present invention relates to cardiac performance, in particular to regulating cardiac performance via recombinant troponin I (TnI) protein and nucleic acids encoding recombinant TnI. The present invention provides nucleic acids encoding gain of function TnI proteins (e.g., cTnlA164H), vectors containing such nucleic acids, host cells containing such vectors, transgenic animals carrying a gain of function TnI protein (e.g., a cTnlA164H transgene), and therapeutic agents (e.g., comprising recombinant TnI, TnI analogues, synthetic TnI, or the like) or agents for gene therapy of heart failure or disease for research and therapeutic uses.
Claims3
An isolated nucleic acid sequence encoding a troponin I (TnI) protein comprising the amino acid sequence set forth in SEQ ID NO:13, wherein the Ala residue at position 43 is substituted with a His residue, and wherein said His residue permits said TnI protein to preserve contractile force during ischemic events, reperfusion injury, or other damage to cardiac tissues.
