| Research Abstract |
Organisms regulate multiple physiological functions such as respiration and metabolism under hypoxic conditions to maintain homeostasis. It still remains to be understood what is the molecule playing a role as an' oxygen sensor' in vivo. In the present study, we have focused on the hypoxia-dependent protein complex(hypoxia complex) and characterized one of its components, PRP19. We are able to demonstrate the molecular mechanism underlying i) the hypoxic cell death which is inhibited by PRP19 and ii) the transcriptional suppression which leads to the downregulation of PRP19.
