Anti-iASPP Antibody

Cat. Num. AAA4156987

• Reactivity: Human, Mouse, Bovine
• Applications: Western Blot, ELISA
• Purity: Affinity Purified
• Synonyms: iASPP; Polyclonal Antibody; Anti-iASPP Antibody; anti-iASPP antibody

• Host: Rabbit
• Reactivity: Human, Mouse, Bovine
• Clonality: Polyclonal
• Isotype: IgG
• Specificity: This affinity-purified antibody is directed against the human iASPP protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification. A BLAST analysis was used to suggest cross reactivity with iASPP proteins from human, dog and mouse sources. Expect reactivity against both isoform 1 and isoform 2. Partial reactivity may occur against iASPP from bovine. Reactivity against homologues from other sources is not known.
• Purity/Purification: Affinity Purified
• Form/Format: Liquid; PBS, pH 7.4 with 0.05% sodium azide.
• Concentration: 1ug/ul (varies by lot)

• Applicable Applications for anti-iASPP antibody: Western Blot (WB), ELISA (EIA)
• Application Notes: This affinity purified antibody has been tested for use in ELISA and by western blot. Specific conditions for reactivity should be optimized by the end user. Expect bands approximately 100 kDa and 50 kDa in size corresponding to isoforms 1 and 2 respectively of iASPP protein by western blotting in the appropriate cell lysate or extract.
• Immunogen: This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to amino acids 780-797 of human iASPP (isoform 1) protein.
• Preparation and Storage: This product is stable for several weeks at 4 degree C as an undiluted liquid. Dilute only prior to immediate use.; For extended storage, aliquot contents and freeze at-20 degree C or below. Avoid cycles of freezing and thawing. Expiration date is one (1) year from date of receipt.

ASPP proteins (ASPP1, ASPP2 and iASPP) represent a new family of p53 binding proteins. ASPP1 and ASPP2 bind and enhance p53-mediated apoptosis. In contrast, the third member, iASPP, functionally inactivates p53. iASPP (also called protein phosphatase 1 regulatory (inhibitor) subunit 13 like protein, Inhibitor of ASPP protein, Protein iASPP, PPP1R13B-like protein and NFkB-interacting protein 1) plays a central role in regulation of apoptosis and transcription via its interaction with NF-kappa-B and p53/TP53 proteins. iASPP blocks transcription of HIV-1 virus by inhibiting the action of both NF-kappa-B and SP1. This protein also inhibits p53/TP53 function, possibly by preventing the association between p53/TP53 and ASPP1 or ASPP2, and therefore suppressing the subsequent activation of apoptosis. iASPP is predominantly a cytoplasmic protein (isoform 1) but can also be found in the nucleus (isoform 2). iASPP is highly expressed in heart, placenta and prostate and is weakly expressed in brain, liver, skeletal muscle, testis and peripheral blood leukocyte. The N-terminal region of isoform 1 is required for cytoplasmic localization. Defects in iASPP may be a cause of certain breast cancers and the protein is overexpressed in many patients suffering from breast carcinomas and expressing a wild-type p53/TP53 protein.
