YWHAB (tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein, β) is one the seven isoforms of 14-3-3 protein family. This gene is present on human chromosome 20q13.1, has six exons, and is highly expressed in mammalian brain. 14-3-3 proteins exist as dimers, are acidic in nature, and are ubiquitously expressed. They are phosphoserine/threonine-binding proteins, and are highly conserved.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)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.

YWHAB (tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein, β) is involved in the control of cell cycle, diffusion and migration. It interacts with ADAM22, which might influence neuronal function and development. It is involved in the differentiation of osteoblasts, and bone formation. This is achieved by the phosphorylation and activation of YWHAB by homodimerisation of Ror2 tyrosine kinase receptor. This gene is up-regulated in vulvar squamous cell carcinoma, and is linked with poor prognosis. It is also up-regulated in gastric cancer, and might have potential as a biomarker for diagnosis and prognosis of the same.
Features and Benefits
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:
- 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.
Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
