Tumor Necrosis Factor Alpha Induced Protein 1 (TNFaIP1)

TNFAIP1 was identified as a gene whose expression can be induced by the tumor necrosis factor alpha (TNF) in umbilical vein endothelial cells. Studies of a similar gene in mouse suggest that the expression of this gene is developmentally regulated in a tissue-specific manner.

Wolf et al. (1992) characterized a novel cDNA by differential screening of a tumor necrosis factor-alpha (TNFA)-stimulated umbilical vein endothelial cell library.The protein product is involved in the primary response of the endothelium to TNF. The 3.5-kb transcript was found to be expressed in a developmentally regulated, tissue-specific manner. The gene, present in single copy, was located in the 17q22-q23 region by in situ hybridization.
