    basic FUNCTION
  • being an essential mediator of TP53-dependent apoptosis
  • important component of the innate immune response of cells to viral infection, leading to enhanced cellular apoptosis that may play a role in limiting viral dissemination
  • with BCL2L11, establish a connection between FKHRL1 and mitochondria, and both BH3-only proteins are critically involved in FKHRL1-induced apoptosis in neuroblastoma
  • may play an important role in the progression of pancreatic cancer
  • suppressor of Myc-induced lymphomagenesis
  • HIF1A-induced proapoptotic gene that mediates hypoxic cell death by generation of ROS
  • promotes activation of caspases and apoptosis
  • promotes mitochondrial membrane changes and efflux of apoptogenic proteins from the mitochondria
  • promotes proteasomal degradation of MCL1
  • competes with BAK1 for binding to MCL1
  • causes mitochondrial fragmentation
  • role in mitochondrial dynamics and cell death
  • having proapoptotic activity and functions downstream of the TP53-mediated apoptotic pathway, to selectively induce apoptosis in tumor cells
  • TP53 transcriptional target involved in the response to DNA-damaging agents
  • participated in triggering mitochondrial dysfunction in multiple apoptotic pathways through distinct mechanisms
  • crucial regulator of osteoclast apoptosis
  • plays a critical role in the regulation of the number of osteoclasts, which may be determined by the level of osteoclast differentiation or survival
  • BIK is a stronger inducer of apoptosis than PMAIP1, and when expressed simultaneously, a combinative effect was observed
  • a function of PMAIP1 was at least in part neutralization of induced myeloid leukemia cell differentiation protein (MCL1) in neutrophils and progenitors
  • apoptosis regulated by BCL2L11- and PMAIP1-driven loss of MCL1 is thus the final step in neutrophil differentiation, required for the termination of neutrophil function and neutrophil-dependent inflammation
  • is involved in the modulation of MCL1 expression
  • triggers the degradation of MCL1 at the mitochondria according to the exclusive location of PMAIP1 at this compartment
  • apoptosis, regulated by PMAIP1, is a critical factor for the selection of high-affinity clones during B cell expansion after antigen triggering
  • sensor of 26S proteasome integrity
  • BCL2L1, and PMAIP1 co-ordinately regulate oxidative stress-induced apoptosis
  • PMAIP1 and, albeit to a lesser extent, BBC3 are essential for DNA damage induced TP63-mediated killing of primordial follicle oocytes
  • PMAIP1 and BBC3 are critical for DNA damage-induced, TP63-mediated oocyte apoptosis
  • important regulator of the number of memory cells formed during infection
  • CELLULAR PROCESS cell life, cell death/apoptosis

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting with MCL1 and BAX
  • strongly upregulated and became associated with both MCL1 and BCL2L11 during apoptosis induced by proteasome inhibition
  • interaction with HRAS (HRAS-induced expression of PMAIP1 and Beclin-1 promotes autophagic cell death) (
  • interacting with HSPA5 (HSPA5 confers resistance to apoptosis induced by BIK and PMAIP)
  • favors the interaction between MCL1 and HUWE1 and consequently affects MCL1 ubiquitination
  • controls HUWE1-dependent MCL1 ubiquitination through the regulation of the MCL1/USP9X interaction
  • PMAIP1 band BBC3 are target genes for TP53
  • TP63 but not TP53 is essential for DNA damage triggered transcriptional induction of BBC3 and PMAIP1 in primordial follicle oocytes
  • TP63 acts via transcriptional induction of the BH3-only proteins, BBC3 and PMAIP1 to cause apoptosis of DNA-damaged primordial follicle oocytes
  • BBC3 like BCL2L11, PMAIP1, is able to act as a direct BAK1 activator
  • MTD domain of PMAIP1 causes mitochondrial damage by opening mitochondrial permeability transition pore (mPTP) through VDACs, especially VDAC2, during necrotic cell death
  • cell & other

    ANIMAL & CELL MODELS
  • mice lacking Noxa exhibit a severe osteoporotic phenotype due to an increased number of osteoclasts
  • upon influenza infection Noxa(-/-) mice generate a memory compartment of increased size and clonal diversity
  • Noxa(-/-) mice mount low affinity antibody responses compared with wild-type animals
