Gene Information
human ... TARDBP(23435)
General description
TAR DNA binding protein (TARDBP) is a DNA and RNA binding transcription repressor and regulator of pre-mRNA splicing and translation. TARDBP binds to the regulatory element TAR found in the transcription initiation site of the HIV-1 gene Tat; consequently TARDBP is an active repressor of chromosomally integrated HIV-1 tat. TARDBP also regulates alternative splicing of CFTR and apo-II genes. A defective form of TARDBP is associated with amyotrophic lateral sclerosis (ALS).
Specificity
Anti-TARDBP (AB1) polyclonal antibody reacts with bovine, human, mouse, rat, chicken, and canine TAR DNA binding protein(s).
Immunogen
Synthetic peptide directed towards the N terminal region of human TARDBP
Application
Anti-TARDBP (AB1) polyclonal antibody is used to tag TAR DNA binding protein for detection and quantitation by Western blotting and in plasma by immunohistochemical (IHC) techniques. It is used as a probe to determine the roles of TAR DNA binding protein in the repression of gene expression and regulation of pre-mRNA splicing and translation.
Biochem/physiol Actions
HIV-1, the causative agent of acquired immunodeficiency syndrome (AIDS), contains an RNA genome that produces a chromosomally integrated DNA during the replicative cycle. Activation of HIV-1 gene expression by the transactivator Tat is dependent on an RNA regulatory element (TAR) located downstream of the transcription initiation site. TARDBP is a transcriptional repressor that binds to chromosomally integrated TAR DNA and represses HIV-1 transcription.HIV-1, the causative agent of acquired immunodeficiency syndrome (AIDS), contains an RNA genome that produces a chromosomally integrated DNA during the replicative cycle. Activation of HIV-1 gene expression by the transactivator Tat is dependent on an RNA regulatory element (TAR) located downstream of the transcription initiation site. The protein encoded by this gene is a transcriptional repressor that binds to chromosomally integrated TAR DNA and represses HIV-1 transcription. In addition, this protein regulates alternate splicing of the CFTR gene. A similar pseudogene is present on chromosome 20.

Previous histopathologic studies of sporadic inclusion body myositis (sIBM) identified sarcoplasmic aggregation and myonuclear depletion of the predominantly nuclear heterogeneous nuclear ribonucleoprotein (hnRNP) TDP-43 in sIBM myofibers. Here, we examined sIBM muscle for abnormalities in two other hnRNPs hnRNPA1 and

TDP-43 (also known as TARDBP) is a pathological signature protein of neurodegenerative diseases, with TDP-43 proteinopathies including frontotemporal lobar degeneration (FTLD)-TDP and amyotrophic lateral sclerosis (ALS)-TDP. These TDP-43 proteinopathies are characterized by cytoplasmic insoluble TDP-43-positive aggregates in the diseased cells

Amyotrophic lateral sclerosis (ALS) is a disease caused by motor neuron degeneration. Recently, a novel SIGMAR1 gene variant (p.E102Q) was discovered in some familial ALS patients. We address mechanisms underlying neurodegeneration caused by the mutation using Neuro2A cells overexpressing σ1R(E102Q)
