This PUMA antibody is useful for Western blot and Immunocytochemistry/Immunofluorescence. By WB a band at ~16 kDa is seen, representing the beta form of PUMA. Reactivity against the alpha form of PUMA is unknown.
The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

p53 up-regulated modulator of apoptosis
PUMA (p53 upregulated modulator of apoptosis) belongs to pro-apoptotic members of Bcl2 family's BH3-only subgroup, and besides its most critical role as mediator of p53/TP53-dependent/-independent apoptosis, it acts as a regulator of ER stress-induced neuronal apoptosis also. PUMA is expressed ubiquitously and predominately localizes to mitochondria where it execute induction of cytochrome c release. PUMA mediates apoptosis via direct binding with anti-apoptotic members of the Bcl-2 family and is capable of interacting with MCL1, BCL2A1, BCL2 and BCL2L1/BCL-XL. PUMA binding to inhibitory members of Bcl-2 family (Bcl-2-like proteins) leads to Bax and/or Bak displacement mediated activation and formation of pore-like structures over mitochondrial membrane, which permeabilizes the outer mitochondrial membrane, resulting in mitochondrial dysfunction and caspase activation. PUMA is induced by p53, DNA damage, glucocorticoid treatment, deprivation of growth factors etc. and through ER stress in a DDIT3/CHOP-dependent manner. PUMA has been reported to involve in multiple physiological and pathological processes, including immune response, cancer, neurodegenerative diseases and bacterial as well as viral infections.

Altered expression of BCL2 in cancer Similar to other cell processes, the balance between cell survival and cell death is an important equilibrium that when altered expression of genes can lead to a variety of disease. For example, too little cell death can promote cell overgrowth a... Read full blog post.
Understanding Noxa Regulation of Apoptosis Noxa is a pro-apoptotic gene belonging to the Bcl2 protein family that is unique in that it contains only BH3 domain. The BH3-only subclass of proteins, including proteins like PUMA and Bim in addition to Noxa, regulate the remaining Bcl-2 family memb... Read full blog post.
