Rabbit anti-Human WBP11 Polyclonal Antibody

Uniprot Id

Q9Y2W2

Target Species

Human

Target Name

WBP11

Target Full Name

WW domain-binding protein 11

Target Function

Activates pre-mRNA splicing. May inhibit PP1 phosphatase activity.

Target Subcellular Location

Nucleus. Cytoplasm. Note=Predominantly located in the nucleus with granular heterogeneous distribution. Excluded from nucleoli in interphase cells, distributed throughout cytoplasm in dividing cells. Colocalized with SC35 and U2B in the nucleus. In the cytoplasm, associates with the intermediate filament protein vimentin.

Target Tissue Specificity

Ubiquitous. Highly expressed in the heart, pancreas, kidney skeletal muscle, placenta and brain (at protein level). Weakly expressed in liver and lung.

Target Background

This gene encodes a nuclear protein, which colocalizes with mRNA splicing factors and intermediate filament-containing perinuclear networks. This protein has 95% amino acid sequence identity to the mouse Wbp11 protein. It contains two proline-rich regions that bind to the WW domain of Npw38, a nuclear protein, and thus this protein is also called Npw38-binding protein NpwBP. The Npw38-NpwBP complex may function as a component of an mRNA factory in the nucleus.
