PUMA Antibody – Rabbit Polyclonal

This gene encodes a member of the BCL-2 family of proteins. This family member belongs to the BH3-only pro-apoptotic subclass. The protein cooperates with direct activator proteins to induce mitochondrial outer membrane permeabilization and apoptosis. It can bind to anti-apoptotic Bcl-2 family members to induce mitochondrial dysfunction and caspase activation. Because of its pro-apoptotic role, this gene is a potential drug target for cancer therapy and for tissue injury. Alternative splicing results in multiple transcript variants.

PUMA: Essential mediator of p53/TP53-dependent and p53/TP53- independent apoptosis. Interacts with MCL1 and BCL2A1. Interacts with BCL2 and BCL2L1/BCL-XL. By DNA damage, glucocorticoid treatment, growth factor deprivation and p53/TP53. Ubiquitously expressed. Belongs to the Bcl-2 family. 4 isoforms of the human protein are produced by alternative splicing.
