Tumor Necrosis Factor Alpha Induced Protein 2 (TNFaIP2)

The TNFAIP2 gene was induced in HUVECs in response to the proinflammatory molecules TNF, IL1B , and lipopolysaccharide. TNFAIP2 demonstrated the characteristics of a primary response gene in its rapid and substantial induction in the absence of intermediary protein synthesis. The authors found that TNFAIP2 transcription was induced during capillary tube formation in vitro. Northern blot analysis detected a 4.2-kb human TNFAIP2 transcript. During mouse development, expression of the Tnfaip2 transcript varied in a temporal fashion that was organ-specific. The TNFAIP2 cDNA encodes a predicted 654-amino acid protein with a single N-linked glycosylation site; stretches of glutamates, lysines, and alanines near the N terminus; and 4 glutamines near the C terminus.
