Target

  • Function
    Probably involved in formation of autophagosomal vacuoles (autophagosomes).
  • Tissue specificity
    Most abundant in heart, brain, skeletal muscle and testis. Little expression observed in liver.
  • Sequence similarities
    Belongs to the MAP1 LC3 family.
  • Post-translational
    modifications
    The precursor molecule is cleaved by APG4B/ATG4B to form LC3-I. This is activated by APG7L/ATG7, transferred to ATG3 and conjugated to phospholipid to form LC3-II.
  • Cellular localization
    Cytoplasm > cytoskeleton. Endomembrane system. Cytoplasmic vesicle > autophagosome membrane. LC3-II binds to the autophagic membranes.
