A neuroscientist who studies ion channels is seeking understudied proteins for a student project. Filtering to targets listed by the IDG Consortium as targets of interest (https://druggablegenome.net/IDGProteinList), in the ion channel family, with a nervous system phenotype as described by the Mouse Phenotype Ontology from the Jackson Laboratory yields 16 potential targets of interest. The refined list view is shown in Figure 9.
