Description

This is a peptide mapping to the carboxy terminus of human TRAIL. Several members of the growing TNF superfamily can regulate the elimination of immune cells by inducing apoptosis (1). TRAIL (TNF-related apoptosis-inducing ligand) or APO-2L is a member of the TNF superfamily that induces apoptosis by activating the death receptors DR4 and DR5 (2,3). TRAIL is attracting great interesting as an anti-cancer agent because it can induce apoptosis in a broad range of tumor cells, but only rarely in non-transformed cells, and independently of p53 status (2&4). For a time it was a it was unclear how TRAIL could induce apoptosis in tumor cells but not in non-transformed cells, while both of the cell types expressed the DR4 and DR5 death receptors. The discovery that DcR1 or TRID are mostly expressed on normal cells but not in most cancer cell lines helped to solve the puzzle, because these proteins act as decoys for the TRAIL protein (5).

Applications Reported

For research use only, not for diagnostic or therapeutic use. This blocking peptide has been reported for use in competition studies.
