Function
DNA and RNA-binding protein which regulates transcription and splicing. Involved in the regulation of CFTR splicing. It promotes CFTR exon 9 skipping by binding to the UG repeated motifs in the polymorphic region near the 3'-splice site of this exon. The resulting aberrant splicing is associated with pathological features typical of cystic fibrosis. May also be involved in microRNA biogenesis, apoptosis and cell division. Can repress HIV-1 transcription by binding to the HIV-1 long terminal repeat. Stabilizes the low molecular weight neurofilament (NFL) mRNA through a direct interaction with the 3' UTR. -
Tissue specificity
Ubiquitously expressed. In particular, expression is high in pancreas, placenta, lung, genital tract and spleen. -
Involvement in disease
Defects in TARDBP are the cause of amyotrophic lateral sclerosis type 10 (ALS10) [MIM:612069]. ALS is a neurodegenerative disorder affecting upper and lower motor neurons and resulting in fatal paralysis. Sensory abnormalities are absent. Death usually occurs within 2 to 5 years. The etiology of ALS is likely to be multifactorial, involving both genetic and environmental factors. The disease is inherited in 5-10% of the cases. -
Sequence similarities
Contains 2 RRM (RNA recognition motif) domains. -
Domain
The RRM domains can bind to both DNA and RNA. -
Post-translational
modificationsHyperphosphorylated in hippocampus, neocortex, and spinal cord from individuals affected with ALS and FTLDU.
Ubiquitinated in hippocampus, neocortex, and spinal cord from individuals affected with ALS and FTLDU.
Cleaved to generate C-terminal fragments in hippocampus, neocortex, and spinal cord from individuals affected with ALS and FTLDU. -
Cellular localization
Nucleus. In patients with frontotemporal lobar degeneration and amyotrophic lateral sclerosis, it is absent from the nucleus of affected neurons but it is the primary component of cytoplasmic ubiquitin-positive inclusion bodies. - Information by UniProt

Western blot - Anti-TDP43 antibody (ab41881)
Lane 1: Wild-type HAP1 cell lysate (40 µg)
Lane 2: TDP43 knockout HAP1 cell lysate (40 µg)
Lane 3: HeLa cell lysate (40 µg)
Lane 4: Jurkat cell lysate (40 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab41881 observed at 48 kDa. Red - loading control, ab8245, observed at 37 kDa.ab41881 was shown to specifically react with TDP43 when TDP43 knockout samples were used. Wild-type and TDP43 knockout samples were subjected to SDS-PAGE. Ab41881 and ab8245 (loading control to GAPDH) were diluted at 1 µg/mL and 1/10000 dilution respectively and incubated overnight at 4C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
