PERP, Blocking Peptide (PIGPC1, THW), Purified

Synthetic peptide (EDDLLGNAKPRYFYTSA) corresponding to amino acids 175 to 193 of human PERP, which differ from the mouse sequence by three amino acids (7-9). The p53 tumor-suppressor gene integrates numerous signals that control cell life and death. Several novel molecules involved in p53 network, including CHK2 (1), p53R2 (2), p53AIP1 (3), Noxa (4), PIDD (5), PID/MTA2 (6), MTBP (7) and PERP (8), were identi?ed and their genes were cloned recently. PERP, also termed PIGPC1 and THW, is a plasma membrane protein (8-10). p53 binds to the promoter of PERP and transcriptionally activates PERP gene then the translated PERP protein mediates the p53 induced apoptosis (8). The expression of PERP causes cell death. PERP is a mediator of p53 induced apoptosis. PERP has sequence similarity to PMP-22/gas3 and is a new member of the PMP-22/gas3 family (8). , Applications: Suitable for use in ELISA and Western Blot. Other applications not tested., , Storage and Stability: Lyophilized powder may be stored at -20°C. Reconstitute to nominal volume by adding sterile 25% glycerol and store at -20°C. May be stored at 4°C for short-term only. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
