    basic FUNCTION
  • involved in autophagy
  • ATG12-ATG5 conjugate has a novel E3-like activity for protein lipidation in autophagy
  • ATG5-ATG12 conjugate, a key regulator of the autophagic process, plays an important role in innate antiviral immune responses
  • important for B cell survival during development and is differentially required at discrete stages of development in distinct, but closely related, cell lineages
  • involved in normal adipocyte differentiation, suggesting an important role of autophagy in adipogenesis
  • MAP1LC3B and ATG5 are not required for initiation of autophagy but mediate phagophore expansion and autophagosome formation
  • required in antigen presentation by dendritic cells
  • with ATG12, ATG2B, ATG9B, are autophagy-related genes, having mononucleotide repeats with seven or more nucleotides
  • regulates the formation of MYD88 condensed structures through association with MYD88 and eventually exerts a modulatory effect on MYD88-dependent signaling
  • CELLULAR PROCESS cell life, cell death/apoptosis
    PHYSIOLOGICAL PROCESS
    text highly expressed in apoptotic cells
    PATHWAY
    metabolism
    signaling
    involved in ATG5/ATG7-dependent conventional pathway for macroautophagy
    a component
  • conjugation of the K-130 to the G-140 of APG12 is a covalent modification that is essential for autophagy
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • binding to ATG12
  • direct interaction between ATG5 and ATG16L1 is crucial to the performance of their roles in autophagy
  • single known conjugation target of ATG12
  • ATG5, a key regulatory protein of autophagy, inhibits the formation of MYD88 condensed structures
  • cell & other
  • binding to isolation membrane

    ANIMAL & CELL MODELS
    All Atg5-null mice died within 1 day of delivery, the survival time of starved Atg5-deficient neonates (approximately 12 hours) was much shorter than that of wildtype mice (approximately 21 hours). Atg5-deficient neonates exhibited reduced amino acid concentrations in plasma and tissues and displayed signs of energy depletion. Neonates adapt to immediate post-birth starvation by inducing autophagy
