Technical Data
PUMA, alpha (p53 Upregulated Modulator of Apoptosis)
PUMA, (p53 upregulated modulator of apoptosis), is activated by p53 in cells undergoing p53-induced apoptosis (1-2). Localized in the mitochondria PUMA induces cytochrome c release and activates the rapid induction of programmed cell death. PUMA interacts with Bcl2 (3), Bcl-XL, Bcl2-like-1 protein and promotes mitochondrial translocation and multimerization of BAX. PUMA also plays a role in mediating p53-induced cell death through the cytochrome c/APAF1-dependent pathway (2). Two isoform of PUMA are known; PUMA-alpha and PUMA-beta.

Suitable for use in Flow Cytometry, Western Blot, Immunoprecipitation, Immunohistochemistry and Immunocytochemistry. Other applications not tested.
