PMAIP1 Antibody – Rabbit Polyclonal

NOXA: Promotes activation of caspases and apoptosis. Promotes mitochondrial membrane changes and efflux of apoptogenic proteins from the mitochondria. Contributes to p53/TP53-dependent apoptosis after radiation exposure. Promotes proteasomal degradation of MCL1. Competes with BAK1 for binding to MCL1 and can displace BAK1 from its binding site on MCL1. Competes with BIM/BCL2L11 for binding to MCL1 and can displace BIM/BCL2L11 from its binding site on MCL1. Interacts with MCL1, BCL2A1 and BAX. Up-regulated by p53/TP53, phorbol esters, double- stranded RNA, IFNB1/IFN-beta and viruses. Highly expressed in adult T-cell leukemia cell line. Belongs to the PMAIP1 family.
