Proximal axonal polarity as well as assembly of the AIS and normal morphogenesis of nodes of Ranvier all require a heretofore uncharacterized alternatively spliced giant exon of ankyrin-G (AnkG). This exon has sequence similarity to I-connectin/Titin and was acquired after the first round of whole-genome duplication by the ancestral ANK2/ANK3 gene in early vertebrates before development of myelin. Non-specific knockdown of Ank3 completely abolishes AIS clustering of AnkG, B4 spectrin, VGSC, and NF186. Rescue with 480-kDA isoform (with giant exon; MmuEX0004933) completely restores this phenotype, whereas rescue with the 270-kDa isoform (with a massive ALTD in the giant exon) partially restores the phenotype. Rescue with 190-kDa isoforms fails to restores any part of the phenotype. Specific knockdown of the 480-kDa isoform completely abolishes AnkG staining at the AIS as well as clustering of its associated binding partners, _4 spectrin, VGSC, and NF186.
