Gene Information

General description

Monoclonal Anti-ASPP2 (mouse IgG1 isotype) is derived from the hybridoma DX 54.10 produced by the fusion of mouse myeloma cells (SP2/0 cells) and splenocytes from BALB/c mice. Apoptosis-stimulating protein of p53 (ASPP) family of proteins contains three members, ASPP1, ASPP2 and iASPP, which interact via their C-terminal region with p53 and modulate its activity.

Specificity

Monoclonal Anti-ASPP2 recognizes human and mouse ASPP2. The epitope recognized by the antibody resides within amino acids 691-1128 of human ASPP2.

Immunogen

fragment of human ASPP2 (amino acids 691-1128).

Application

Mouse Monoclonal Anti-ASPP2 has been used for immunofluorescence analysis. The antibody can also be used for immunocytochemistry, immunoprecipitation and microarray applications.
Western blot analysis of Hek293 or 3T3-L1 adipocyte cell lysates was performed using monoclonal mouse anti-ASPP2 as the primary.

Biochem/physiol Actions

ASPP2 is a tumor suppressor that activates p53. ASPP2 also regulates Par-3 which subsequently modulates the proliferation and polarity of neural progenitor cells during CNS development. Furthermore, ASPP2 interacts with active Ras to induce p53 mediated cell death. ASPP2 is known to function as a biomarker for invasive pituitary adenomas.
Apoptosis-stimulating protein of p53 (ASPP2) enhances the ability of p53 to induce apoptosis ASPP1 and ASPP2 stimulates the transactivation function of p63 and p73 on promoters of different genes such as BCL2 associated X, apoptosis regulator (Bax), p53-inducible gene 3 (PIG3) and p53 upregulated modulator of apoptosis (PUMA), but not mouse double minute 2 homolog (Mdm2) or p21WAF-1/CIP1.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
