Rabbit anti Human iASPP antibody detects human inhibitor of apoptosis stimulating protein of p53 (iASPP), which plays a central role in regulation of apoptosis and transcription via its interaction with NFkB and p53 proteins. At present, the iASPP gene is thought to encode three isoforms; isoform 1 is predominantly located in the cytoplasm, whilst isoforms 2 and 3 are nuclear proteins. iASPP is highly expressed in the heart, placenta and prostate.
iASPP has been shown to have oncogenic properties in human breast carcinomas.
