Blocking Peptide for anti-p53 Upregulated Modulator of Apoptosis/Bcl 2 Binding Component 3 (PUMA/bbc3) (CT), Catalog #: P1001-32W
Synthetic peptide (PLPRGHRAPEMEPN) corresponding to amino acids 180 to 193 of human PUMA-a (1).
Apoptosis is related to many diseases and development. The p53 tumor-suppressor protein induces apoptosis through transcriptional activation of several genes. A novel p53 inducible pro-apoptotic gene was identi?ed recently and designated PUMA (for p53 upregulated modulator of apoptosis) and bbc3 (for Bcl-2 binding component 3) in human and mouse (1-3). PUMA/bbc3 is one of the pro-apoptotic Bcl-2 family members including Bax and Noxa, which are also transcriptional targets of p53. The PUMA gene encodes two BH3 domain-containing proteins termed PUMA-a and PUMA-b (1). PUMA proteins bind Bcl-2, localize to the mitochondria, and induce cytochrome c release and apoptosis in response to p53. PUMA may be a direct mediator of p53-induced apoptosis.
Applications: Suitable for use in ELISA and Western Blot. Other applications not tested.
Storage and Stability: Lyophilized powder may be stored at -20 degrees C. Reconstitute to nominal volume by adding sterile 25% glycerol and store at -20 degrees C.
