caution:PubMed:12740394 has shown that the protein is cleaved at Lys-122 but PubMed:15355958 has shown that the cleavage site is at Gly-120 as in other mammalian orthologs. ,function:Probably involved in formation of autophagosomal vacuoles (autophagosomes) . ,PTM: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. ,similarity:Belongs to the MAP1 LC3 family. ,subcellular location:LC3-II binds to the autophagic membranes. ,subunit:3 different light chains , LC1 , LC2 and LC3 , can associate with MAP1A and MAP1B proteins. ,tissue specificity:Most abundant in heart , brain , skeletal muscle and testis. Little expression observed in liver. ,
