Figure 5: A schematic representation of the interactions between
troponin and other thin filament components. The potential
actin-tropomyosin-binding portions, which are not included in
the current structural model, are schematically drawn: TnT1 and
C-TnT are yellow ellipsoids, and the inhibitory region (IR) and
the C terminus of TnI (C-TnI) are blue ellipsoids. The actin and
the tropomyosin strands are in green and brown, respectively.
The black arrows indicate the interactions between troponin and
tropomyosin-actin.
