Figure 7.

Models demonstrating a potential mechanism involved in the CaM and FHF modulation of the persistent current mediated through the putative interaction between III-IV linker and CTD. Structures of the CTD complexes containing FHF/CaM or CaM only overlaid on NaVPas show FHF (A) and CaM (B) positioned on CTD to stabilize the interaction between III-IV linker and CTD. (A) Structure of NaVPas (PDB accession no. 5X0M) overlaid with the NaV1.5 CTD in complex with FGF13 (PDB accession no. 4DCK). (B) Structure of NaVPas overlaid with the NaV1.5 CTD in complex with CaM (PDB accession no. 4OVN).
