Extended Data Fig. 11: Conservation analysis and potential protein interaction sites.

a, Conservation analysis66 of NALCN highlighting the FAM155A docking site (FAM155A in grey surface rendering). Sequences used for analysis: Homo sapiens, Mus musculus, Rattus norvegicus, Xenopus tropicalis, Ictalurus punctatus, Danio rerio, Gallus gallus, Columba livia, Drosophila melanogaster, Aedes albopictus, Caenorhabditis elegans, Anisakis simplex. b, Superposition of NALCN, NaV1.7 (PDB: 6J8G), CaV1.1 (PDB: 6JPA), CaV3.1 (PDB: 6KZP) and HCN1 (PDB: 5U6P) based on the S5 segment, with only the S5 and S4-S5 linkers shown for clarity. c, Conservation analysis (as in panel a) shown for the NALCN CTD-region.
