RFI antibody
No associated image currently available
Rabbit anti Human RFI antibodydetects human Ring Finger homologous to Inhibitor of apoptosis protein (hRFI), an anti-apoptotic protein which has been shown to be a novel modulator of NF-kB activation, leading to the upregulation of Bcl2 and BclXL. It is also thought to possess E3 ubiquitin protein ligase activity and has been shown to target caspases 8 and 10 for proteasomal degradation.
hRFI is expressed ubiquitously, and has been localized to both the nucleus and the cytoplasm. hRFI is also expressed in oesophageal, gastric and colorectal cancers, suggesting a possible association between hRFI and the development of digestive tract cancers.
