Gene Information

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.

ASPP1 and ASPP2 are both proteins that interact with p53 and enhance its ability to induce apoptosis by selectively elevating the expression of proapoptotic p53-responsive genes. iASPP(RAI) is a third member of the family that is the most conserved inhibitor

Among the diverse co-regulatory relationships between transcription factors (TFs) and microRNAs (miRNAs), feedback loops have received the most extensive research attention. The co-regulation of TFs and miRNAs plays an important role in colorectal cancer (CRC) growth. Here, we show that
