Opis ogólny
Polyglutamine tract binding protein 1 (PQBP1) with a WW domain plays an important role in regulation of transcription activity. WW domain binds to proline-rich motifs in other proteins. In addition to the WW domain, it also possesses a polyglutamine-binding region (in polar-amino-acid–rich domain) and a DR/ER stretch involved in transcriptional control. It is ubiquitously expressed in neurons throughout the brain specifically in hippocampus, cerebellar cortex and olfactory bulb. It localizes in the nucleus.

Zastosowanie
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.
The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Działania biochem./fizjol.
During transcriptional control, PQBP1 (polyglutamine binding protein 1) binds to the polyQ region of the transcription factor BRN2 (brain-specific homeobox/POU domain protein 2) to silences transcription. Mutation in PQBP1 causes X-linked mental retardation, microcephaly, short stature, spastic paraplegia and midline defects. It interacts with RNA polymerase II and other transcription factors. In addition, it has been reported in RNA transport or cytoplasmic RNA processing.
Cechy i korzyści
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

Polyglutamine(Q) tract binding protein-1 (PQBP-1) was isolated on the basis of its interaction with polyglutamine tracts and localizes predominantly to the nucleus where it suppresses transcriptional activation by a neuron-specific transcription factor, Brn-2. Its C-terminal domain is highly conserved and

Polyglutamine-binding protein 1 (PQBP1) is a highly conserved protein associated with neurodegenerative disorders. Here, we identify PQBP1 as an alternative messenger RNA (mRNA) splicing (AS) effector capable of influencing splicing of multiple mRNA targets. PQBP1 is associated with many splicing

Splicing factor polyglutamine binding protein-1 (PQBP1) is abundantly expressed in the central nervous system during development, and mutations in the gene cause intellectual disability. However, the roles of PQBP1 in cancer progression remain largely unknown. Here, it is shown that

A novel gene, designated PQBP-1, which encodes a 265 residue protein that binds to the polyglutamine tract of the brain-specific transcription factor Brn-2, was identified. PQBP-1, which also interacts with the polyglutamine tract of triplet repeat disease gene products, binds

We found mutations in the gene PQBP1 in 5 of 29 families with nonsyndromic (MRX) and syndromic (MRXS) forms of X-linked mental retardation (XLMR). Clinical features in affected males include mental retardation, microcephaly, short stature, spastic paraplegia and midline defects.
