CC   -!- FUNCTION: Probably involved in formation of autophagosomal
CC       vacuoles (autophagosomes).
CC   -!- SUBUNIT: 3 different light chains, LC1, LC2 and LC3, can associate
CC       with MAP1A and MAP1B proteins (By similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Intracytoplasmic membrane; Lipid-
CC       anchor. Cytoplasmic vesicle, autophagosome membrane; Lipid-anchor.
CC       Note=LC3-II binds to the autophagic membranes.
CC   -!- ALTERNATIVE PRODUCTS:
CC       Event=Alternative splicing; Named isoforms=2;
CC       Name=1;
CC         IsoId=Q9H492-1; Sequence=Displayed;
CC       Name=2;
CC         IsoId=Q9H492-2; Sequence=VSP_013660;
CC         Note=No experimental confirmation available;
CC   -!- TISSUE SPECIFICITY: Most abundant in heart, brain, liver, skeletal
CC       muscle and testis but absent in thymus and peripheral blood
CC       leukocytes.
CC   -!- PTM: The precursor molecule is cleaved by APG4B/ATG4B to form the
CC       cytosolic form, LC3-I. This is activated by APG7L/ATG7,
CC       transferred to ATG3 and conjugated to phospholipid to form the
CC       membrane-bound form, LC3-II.
CC   -!- SIMILARITY: Belongs to the MAP1 LC3 family.
