SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm
	intracellular,nucleus

basic FUNCTION	contributing to glioma carcinogenesis
	involved in the TP53-mediated cell death pathway as a downstream effector of TP53 in brain ischemia/hypoxia
	inhibits Wnt signaling and regulates glioma growth
	inducing apoptosis in ccoperation with SIAH1A
	acting as a mediator between TP53 and BAX in a neuronal death pathway that is activated by DNA damage
	acting synergistically with TRAF2 and inhibits TNF-induced apoptosis through activation of NF-KappaB
	possesses a tumor suppressor activity in glioma cells
	serves as an invaluable marker for competent self-renewing stem cells in a wide array of adult tissues
	PEG3/reporter activity identifies stem/progenitor cells of the adult CNS and can be used to track a self-renewing population

CELLULAR PROCESS	cell life, cell death/apoptosis
