Putative oxidoreductase. May control genotoxic stress-induced cell death. May play a role in TGFB1 signaling and TGFB1-mediated cell death. May also play a role in tumor necrosis factor (TNF)-mediated cell death. May play a role in Wnt signaling (By similarity). Belongs to the short-chain dehydrogenases/reductases (SDR) family.
