TNFAIP8, Tumor necrosis factor alpha-induced protein 8, Head and neck tumor and metastasis-related protein, MDC-3.13, NF-kappa-B-inducible DED-containing protein, SCC-S2, TNF-induced protein GG2-1

Acts as a negative mediator of apoptosis and may play a role in tumor progression. Suppresses the TNF-mediated apoptosis by inhibiting caspase-8 activity but not the processing of procaspase-8, subsequently resulting in inhibition of BID cleavage and caspase-3 activation.
