  • MCH2-alpha, pro-CASP6a
  • its activity is abundant in the neuropil threads, neuritic plaques, and neurofibrillary tangles of sporadic and familial forms of Alzheimer disease brains and in the neurites and nuclei of apoptotic neurons in human fetal and adult ischemic brains
  • active CASP6a may be predominantly responsible for neurodegeneration rather than cell death
    • 4 - 1432 - 204 - 2010 20682790
  • MCH2-beta , pro-CASP6b
  • lacking protease activity
  • contains a catalytic site
  • inhibitor of pro-CASP6a

    HOMOLOGY
    Homologene
    FAMILY caspase family of cysteinyl-aspartate specific proteases
    CATEGORY enzyme
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm,cytosolic
    text stored in the mitochondrial intermembrane space and released into cytosol after appropriate apoptotic stimuli
    basic FUNCTION
  • cleaves poly(ADP-ribose) polymerase, as well as lamins
  • involved in the activation cascade of caspases responsible for apoptosis execution
  • could be an early instigator of neuronal dysfunction
  • regulates B cell activation and differentiation into plasma cells by modifying cell cycle entry
  • playing a role in N-terminal truncation of tau during neurofibrillary tangle evolution and the progression of Alzheimer's disease
  • its activity may be involved in the clinical manifestation of Huntington and Parkinson diseases
  • can be activated and regulated through intramolecular self-cleavage
    • CELLULAR PROCESS cell life, cell death/apoptosis
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component heterodimer of a 18 kDa (p18) and a 11 kDa (p11) subunit
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • CASP3
  • CASP8
  • CASP10
  • IRAK3 is an important target for CASP6 (neutrophils activate alveolar macrophages by producing caspase-6-mediated cleavage of IRAK3)
  • BCL2L2 interacts with BAX and suppresses the CASP6 apoptotic cascade that fosters axonal degeneration
