NR2E3 produces a large isoform encoded in 8 exons and a shorter isoform of 7 exons. The short isoform may have a physhiological role, since intron 7 retention (MmuINT0110513, but normally as APA) for the generation of the short isoform appears to be developmentally regulated and has been identified in transcriptomic analysis at least in humans and mice. The in-frame stop codon at the very beginning of intron 7 is also evolutionary conserved in ten of the eleven vertebrate species considered, pointing to some functionality. This short isoform displays the N-terminal transactivator domain, can bind their target motifs and potentially interact with CRX through the DBD, but would lack the C-terminal domains H10 and AF2 (respectively involved in the dimerization and repression function of NR2E3), which are also highly conserved across species. Note: the short isoform is normally produced by APA, but standard IR would generate the equivalent protein.
