General description
Monoclonal Anti-iASPP (mouse IgG1 isotype) is derived from the hybridoma LXO49, produced by the fusion of mouse myeloma cells (SP2/0 cells) and splenocytes from BALB/c mice immunized with a recombinant protein encoding residues of human iASPP. The ASPP family of proteins contains three members, ASSP1, ASSP2 and iASPP. iASPP is also known as REL associated inhibitor (RAI). iASPP exists as a 100 kDa form and as a 70 kDa form (iASPP/RAI). It is found both in the nucleus and cytoplasm, while iASPP/RAI is mainly cytosolic. PPP1R13L (protein phosphatase 1 regulatory subunit 13 like) codes for iASPP, that is located on human chromosome 19q13.
iASPP is an inhibitory member of the apoptosis-stimulating protein of p53 (ASPP) family. It is an oncoprotein that associates with Ras, E1A and E7 to transform cells.
Application
Monoclonal Anti-iASPP antibody produced in mouse has been used in:
- immunoblotting
- immunocytochemistry
- immunoprecipitation
Mouse monoclonal Anti-iASPP antibody can be used for western blot (0.1-0.2μg/mL using total cell extract of human osteogenic sarcoma), microarray, immunoprecipitation and immunocytochemistry.
Biochem/physiol Actions
PPP1R13L (protein phosphatase 1 regulatory subunit 13 like)/iASPP inhibits p53-mediated cell death. It interacts and inhibits NFkB p65 RelA. It may act as a therapeutic target for bladder cancer (BC). It modulates cell proliferation and apoptosis. iASPP plays a key role in breast cancer and acute leukemia.
Physical form
Solution in 0.01 M phosphate buffered saline containing 15 mM sodium azide.

The transcription factor p53 mediates the apoptosis of post-mitotic neurons exposed to a wide range of stress stimuli. The apoptotic activity of p53 is tightly regulated by the apoptosis-stimulating proteins of p53 (ASPP) family members: ASPP1, ASPP2 and iASPP. We
