Paternally-expressed gene 3 protein (PEG3)

Induces apoptosis in Collaboration with SIAH1A.

Acts as a mediator between p53/TP53 and BAX at a neuronal death pathway that is triggered by DNA damage.

Acts synergistically with TRAF2 and inhibits TNF induced apoptosis through activation of NF-kappa-B (By similarity). Possesses a tumor suppressing activity in glioma cells.
