IHC-FoFr: Use at an assay dependent dilution. (PubMed: 20736350)
Target
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
modifications
Hyperphosphorylated 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.

Immunocytochemistry/ Immunofluorescence - TARDBP antibody (ab41881)
ICC/IF image of ab41881 stained human Hek293 cells. The cells were 4% PFA fixed (10 min), permabilised in 0.1% PBS-Tween (20 min) and incubated with the antibody (ab41881, 5µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).

Immunohistochemistry (PFA perfusion fixed frozen sections) - TARDBP antibody (ab41881)
ab41881 staining TARDBP in murine spinal cord by Immunohistochemistry (PFA perfusion fixed frozen sections).Tissues fixed by 4% paraformaldehyde in phosphate buffer (pH 7.4) were cryoprotected by 30% sucrose in PBS (pH 7.4). Frozen sections (10 µm) of spinal cord tissues from three or more transgenic mice, respectively, were processed for immunofluorescence using ab41881. An Alexa Fluor 594 was used as secondary antibodies to visualize protein. Scale bar 20 µm.TARDBP is localized in the nucleus and forms intranuclear granular structures, arrowheads.
