    • 功能:
      Troponin I is the inhibitory subunit of troponin, the thin filament regulatory complex which confers calcium-sensitivity to striated muscle actomyosin ATPase activity.
    • 基因功能参考文献:
      1. Pim-1 is a novel kinase that phosphorylates cTnI primarily at Ser23/24 and Ser150 in cardiomyocytes, which in turn may modulate myofilament function under a variety of physiological and pathophysiological conditions. PMID: 29544221

      4. Compared to cTnI(WT), both truncations displayed greater Ca(2+)-sensitivity and faster cross-bridge attachment rates at both SLs. Furthermore, cTnI(1-167) slowed MgADP release rate and enhanced cross-bridge binding. Our findings imply that cTnI-MD truncations affect the blocked-to closed-state transition(s) and destabilize the closed-state position of tropomyosin. PMID: 28958680

      22. cTnC, cTnI, cTnT and cTm are not only present in myofilaments of ventricular cardiomyocytes in culture but are also within their nuclei; significantly, these four proteins appear between days 3 and 5 in both myofilaments and nuclei PMID: 22364878
