TDP-43 represses cryptic exon inclusion in the FTD-ALS gene UNC13A

Main. TDP-43, encoded by the TARDBP gene, is an abundant, ubiquitously expressed RNA-binding protein that normally localizes to the nucleus. It has a role in fundamental RNA-processing activities, including RNA transcription, alternative splicing and RNA transport 7.A major splicing regulatory function of TDP-43 is to repress the inclusion of cryptic exons during splicing 2,8-10.
