Gene Information

human ... TARDBP(23435)

General description

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. (provided by RefSeq)
TAR DNA binding protein 43 (TDP-43) belongs to the heterogeneous nuclear ribonucleoprotein family. It is expressed in neurons, glia and other cell types. This gene is located on human chromosome 1p36.

Immunogen

TARDBP (NP_031401.1, 1 a.a. ~ 260 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

Application

Monoclonal Anti-TARDBP antibody has been used in immunohistochemistry and immunoblotting.

Biochem/physiol Actions

TAR DNA binding protein 43 (TDP-43) participates in RNA alternative splicing, stability, transcriptional regulation, mRNA transport and translation. It is associated with Alzheimer′s disease. Mutations in TDP-43 result in proteinaceous inclusions in neurons and are expected to cause frontotemporal dementia or amyotrophic lateral sclerosis.

Physical form

Solution in phosphate buffered saline, pH 7.4
