LC3C Products

FUNCTION: Probably involved in formation of autophagosomal vacuoles (autophagosomes). SUBUNIT: 3 different light chains, LC1, LC2 and LC3, can associate with MAP1A and MAP1B proteins. SUBCELLULAR LOCATION: LC3-I: Cytoplasm. LC3-II: Intracytoplasmic membrane; lipid-anchor. LC3-II binds to the autophagic membranes. TISSUE SPECIFICITY: Most abundant in placenta, lung and ovary. PTM: The precursor molecule is cleaved by APG4B/ATG4B to form the cytosolic form, LC3-I. This is activated by APG7L/ATG7, transferred to ATG3 and conjugated to phospholipid to form the membrane-bound form, LC3-II. SIMILARITY: Belongs to the MAP1 LC3 family.
