Function

PEG3_HUMAN Induces apoptosis in cooperation with SIAH1A. Acts as a mediator between p53/TP53 and BAX in a neuronal death pathway that is activated 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.^[1]

Publication Abstract from PubMed

Human paternally expressed gene 3 protein (PEG3) is a large multi-domain entity with diverse biological functions, including acting as a transcription factor. PEG3 contains twelve Cys2-His2 type zinc finger domains, extended regions of predicted disorder and at the N-terminus a SCAN domain. PEG3 has been identified as partner of the E3 ubiquitin-protein ligase Siah1, an association we sought to investigate. An efficient bacterial recombinant expression system of the human PEG3-SCAN domain was prepared and crystals appeared spontaneously when the protein was being concentrated after purification. The structure was determined at 1.95 A resolution and reveals a polypeptide fold of five helices in an extended configuration. An extensive dimerization interface, using almost a quarter of the solvent accessible surface, and key salt bridge interactions explain the stability of the dimer. Comparison with other SCAN domains reveals a high degree of conservation involving residues that contribute to the dimer interface. The PEG3-SCAN domain appears to constitute an assembly block, enabling PEG3 homo- or heterodimerization to control gene expression in a combinatorial fashion.
