Protein attributes

Sequence length	121 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Probably involved in formation of autophagosomal vacuoles (autophagosomes) By similarity.
Subunit structure	3 different light chains, LC1, LC2 and LC3, can associate with MAP1A and MAP1B proteins By similarity.
Subcellular location	Cytoplasm. Intracytoplasmic membrane; Lipid-anchor. Cytoplasmic vesicle › autophagosome membrane; Lipid-anchorBy similarity. Note= LC3-II binds to the autophagic membranes By similarity.
Post-translational modification	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 By similarity.
Sequence similarities	Belongs to the MAP1 LC3 family.
