| 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. |

| 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). |
