DcR2 (D13H4) Rabbit mAb #8049
|W IP||H Mk||Endogenous||45-60||Rabbit IgG|
Reactivity Key: H=Human Mk=Monkey
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
DcR2 (D13H4) Rabbit mAb recognizes endogenous levels of total DcR2 protein. This antibody may detect an unidentified protein of 30 kDa in some cell lines.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly270 of human DcR2 protein.
Western blot analysis of extracts from 293T cells, mock transfected (-) or transfected with a construct encoding full-length human DcR2 (hDcR2; +), using DcR2 (D13H4) Rabbit mAb.
The tumor necrosis factor receptor family, which includes TNF-RI, Fas, DR3, DR4, DR5, and DR6, plays an important role in the regulation of apoptosis in various physiological systems (1,2). The receptors are activated by a family of cytokines that include TNF, FasL, and TRAIL. They are characterized by a highly conserved extracellular region containing cysteine-rich repeats and a conserved intracellular region of about 80 amino acids termed the death domain (DD). The DD is important for transducing the death signal by recruiting other DD containing adaptor proteins (FADD, TRADD, RIP) to the death-inducing signaling complex (DISC), resulting in activation of caspases.
Death receptor signaling can be controlled by a family of decoy receptors (DcR1, DcR2, and DcR3) that lack a cytoplasmic DD and inhibit death receptor-mediated apoptosis by competing for ligand binding (3-5). Expression of decoy receptors can contribute to chemosensitivity and may provide a mechanism for regulation of apoptosis in certain types of cancer (6-8).
