    text
  • filamentous pattern through the cytoplasm
  • full-length BIRC7 shows diffuse cytoplasmic localization, truncated form is found in a peri-nuclear distribution with marked localization to the Golgi apparatus
  • basic FUNCTION
  • involved in the regulation of apoptosis
  • important determinant for the apoptotic resistance of non-small cell lung cancer cells
  • may exert anti-apoptotic action by activating JNK1 signaling pathway and inhibiting caspase-3 activation
  • may contribute to drug resistance in neuroblastoma, and may be essential for survival of some cancer cells
  • has a role in thrombopoiesis by regulating the apoptotic and antiapoptotic balance in megakaryocyte endoreplication and platelet production
  • BIRC7,CASP3, BIRC5 are closely related to the occurrence and development of prostatic cancer
  • CELLULAR PROCESS cell life, antiapoptosis

    small molecule
    protein
  • inhibitor of downstream caspase, CASP9 (strong), CASP3 (weak) and CASP7
  • can act as an E3 ubiquitin ligase for targeting the degradation of Smac/DIABLO (exhibits E3 ubiquitin ligase activity to degrade the pivotal apoptotic regulator Smac/DIABLO through the ubiquitin-proteasome pathway)
  • new, BIRC7-dependent, apoptotic role for TEAD1
  • cell & other
    REGULATION
    activated by MYCN (MYCN protein may act as a transcriptional activator of BIRC7 expression supporting the notion that, in cells co-expressing these genes, the antiapoptotic effect of BIRC7 may counteract the apoptotic effects associated with MYCN amplification)
    induced by various stimuli
    repressed by Smac/DIABLO
    Other cleaved by effector caspases to produce a truncated form with paradoxical pro-apoptotic activity
