	Western Blot: TRAF-2 Antibody (33A1293) [NB100-56715] - Analysis of TRAF2 in HeLa lysate using TRAF2 antibody at 2 ug/ml.
	Immunohistochemistry-Paraffin: TRAF-2 Antibody (33A1293) [NB100-56715] - Formalin-fixed, paraffin-embedded human transitional cell carcinoma of the urinary bladder stained with TRAF2 antibody at 5 ug/ml. Staining of formalin-fixed tissues is enhanced by boiling tissue sections in 10 mM sodium citrate buffer, pH 6.0 for 10-20 min followed by cooling at RT for 20 min.

Background

Tumor necrosis factor (TNF) induced signaling is mediated through association of TNF receptor (TNFR) with adaptor proteins, such as TNF receptor associated proteins (TRAFs). TRAFs form a family of cytoplasmic adapter proteins that mediate signal transduction from many members of the TNF-receptor superfamily (e.g. RANK, CD30, CD40, etc.) and the interleukin-1 receptor. The carboxy-terminal region of TRAFs is required for self-association and interaction with receptor cytoplasmic domains following ligand-induced oligomerization. Recent molecular cloning studies have lead to identification of six TRAFs (TRAF1-TRAF6). TRAF2 is a 502-amino acid protein. Mutagenic studies suggest that the N-terminal RING finger and two adjacent zinc fingers of TRAF2 are required for NF-kB activation, where as interaction with TNFR is mediated through C-terminus domain. Distinct domains in the N- and -C termini are also required for association with TRAF1 and protein kinase receptor interacting protein (RIP). TRAF2 is involved in cellular resistant to TNF-induced apoptosis. TRAF-2 deficient mice appeared normal at birth, however, they die prematurely, probably due to atrophy of thymus, spleen, muscle mass and lack of TRAF-2's cytoprotective role.
