Hypoxia-inducible gene RTP801 (RTP801)

Target
RTP801
Molecular classification
Stress-response protein
01

Overview

Hypoxia-inducible gene RTP801 encodes a highly conserved stress-response protein that integrates environmental cues like hypoxia into intracellular decisions about growth arrest versus survival/apoptosis mainly through negative regulation of the mTOR/Akt axis. Its function varies with cellular context—from protective antioxidant effects during acute proliferation-associated stresses to pro-apoptotic actions driving pathology when chronically elevated post-differentiation or under persistent insult.
