Background Information

Inhibitor of apoptosis-stimulating protein of p53 (iASPP), encoded by PPP1R13L gene, is often overexpressed in human cancers. The ASPP family includes three members, namely ASPP1, ASPP2, and iASPP, which are specific regulators of p53-, p63-, and p73-mediated apoptosis. ASPP1 and ASPP2 enhance the apoptotic function of p53, whereas iASPP specifically inhibits p53- mediated apoptosis. Overexpression of iASPP is associated with resistance to cisplatin-induced apoptosis and rediation therapy. iASPP plays a pivotal role in regulating cancer cell proliferation and tumor progression. This antibody could both recognize unphosphorylated and phosphorylated iASPP.
