Description_x000D_ General description_x000D_ Plexin B1 (PLXNB1) gene spanning 21kb with 37 exons is mapped to human chromosome 3p21.31. The encoded protein is predominantly expressed in fetal kidney, digestive system, thyroid, prostate and trachea and is also expressed at lower levels in fetal brain, lung, female reproductive system and liver. PLXNB1 is a member of the plexin family and is characterized with a three IPT (Ig-like, plexins, transcription factors) /TIG domains and one Sema domain._x000D_ Immunogen_x000D_ plexin B1 recombinant protein epitope signature tag (PrEST)_x000D_ Application_x000D_ Anti-PLXNB1 antibody produced in rabbit has been used in immunohistochemistry._x000D_ Physical form_x000D_ Solution in phosphate buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Legal Information_x000D_ Prestige Antibodies is a registered trademark of Sigma-Aldrich Co. LLC_x000D_ Biochem/physiol Actions_x000D_ Plexin B1 (PLXNB1) interacts with its ligand semaphorin4D (Sema4D) and induces androgen receptor (AR) transcriptional activity by stimulating translocation of AR to the nucleus. It plays a vital role in in signal transduction, intracellular signaling cascade, multicellular organismal development, cell migration, angiogenesis and positive regulation of axonogenesis. Mutation of the gene or elevated expression of the protein is associated with the pathogenesis of prostate cancer. PLXNB1 inhibits the glioma invasiveness and angiogenesis via controlling the Ras homolog gene family, member A (RhoA) /αvβ3/ phosphoinositide-3-kinase/Akt (PI3K/Akt) signaling pathway and serine-arginine protein kinase 1 (SRPK1).Thus, this protein can be considered as a potential therapeutic target for the glioma invasion and angiogenesis._x000D_ Features and Benefits_x000D_ 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._x000D_ Every Prestige Antibody is tested in the following ways:_x000D_ • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues._x000D_ • Protein array of 364 human recombinant protein fragments._x000D_ • Validated for multiple commonly used applications such as IHC (Immunohistochemistry), IF (Immunofluorescence), and WB (Western Blot)_x000D_ Linkage_x000D_ Corresponding Antigen APREST79469.
