Organism

Mus musculus (Mouse)

Taxonomic identifier

10090 [NCBI]

Taxonomic lineage

Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Glires › Rodentia › Sciurognathi › Muroidea › Muridae › Murinae › Mus › Mus

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 › cytoskeleton. Endomembrane system; Lipid-anchor. Cytoplasmic vesicle › autophagosome membrane; Lipid-anchor By 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.
