SCN5A and ischemia: Human leukocyteantigen F-associated transcript 10 (FAT10) of the small ubiquitin-like proteinfamily binds to lysine residues in the C-terminal fragment of Nav1.5 anddiminishes the binding of Nav1.5 to Nedd4-2, blocking its degradation by the UPSafter an MI and suppresses ischemia-induced VAs [4].
