TNFAIP2, also known as B94, is a TNF-a-regulated gene that is expressed in endothelial cells, peripheral blood cells, and mature sperm. Recently, elevated TNFAIP2 expression was observed in nasopharyngeal carcinoma, and high expression of TNFAIP2 was significantly correlated with higher levels of cell migration, invasion and metastasis, suggesting that TNFAIP2 may serve as a useful prognostic indicator for nasopharyngeal carcinoma. TNFAIP2 has also been implicated as part of the viral-sensing circuit of the innate immune response.Synonyms: Primary response gene B94 protein, Tumor necrosis factor alpha-induced protein 2
