Graph view of Nav Sodium Channel representation in NIFSTD. NIF Molecule defines the relationships among the macromolecule Nav 1.4 sodium channel (bold oval), its auxiliary subunit (Nav Beta), the channel and pore regions (aa sequence), the gene encoding these sequences (SCNA4 gene) and its corresponding chromosome location. The different shadings indicate that the concepts come from different hierarchies within the NIF molecule module. Unlabeled arrows represent “is a” relationship, e.g., Nav1.4 Sodium channel is a Type 1 Sodium channel
