CC   -!- FUNCTION: Ubiquitin-like modifier involved in formation of
CC       autophagosomal vacuoles (autophagosomes). Plays a role in mitophagy
CC       which contributes to regulate mitochondrial quantity and quality by
CC       eliminating the mitochondria to a basal level to fulfill cellular
CC       energy requirements and preventing excess ROS production. In response
CC       to cellular stress and upon mitochondria fission, binds C-18 ceramides
CC       and anchors autophagolysosomes to outer mitochondrial membranes to
CC       eliminate damaged mitochondria. While LC3s are involved in elongation
CC       of the phagophore membrane, the GABARAP/GATE-16 subfamily is essential
CC       for a later stage in autophagosome maturation. Promotes primary
CC       ciliogenesis by removing OFD1 from centriolar satellites via the
CC       autophagic pathway. Through its interaction with the reticulophagy
CC       receptor TEX264, participates in the remodeling of subdomains of the
CC       endoplasmic reticulum into autophagosomes upon nutrient stress, which
CC       then fuse with lysosomes for endoplasmic reticulum turnover. Upon
CC       nutrient stress, directly recruits cofactor JMY to the phagophore
CC       membrane surfaces and promotes JMY's actin nucleation activity and
CC       autophagosome biogenesis during autophagy.
CC       {ECO:0000250|UniProtKB:Q9GZQ8}.
CC   -!- SUBUNIT: 3 different light chains, LC1, LC2 and LC3, can associate with
CC       MAP1A and MAP1B proteins (By similarity). Interacts at microtubules
CC       with CABP1 (via EF-hands 1 and 2) but not with calmodulin. Interacts
CC       with FYCO1 (via C-terminus). Interacts with TP53INP1 and TP53INP2 (By
CC       similarity). Interacts with TBC1D25 (PubMed:21383079). Directly
CC       interacts with SQSTM1; this interaction leads to MAP1LC3B recruitment
CC       to inclusion bodies containing polyubiquitinated protein aggregates and
CC       to inclusion body degradation by autophagy. Interacts with ATG4B,
CC       MAPK15 and BNIP3. Interacts with MAPB1, KEAP1, PCM1, OFD1, CEP131, and
CC       TECPR2. Interacts with TBC1D5. Found in a complex with UBQLN1 and
CC       UBQLN2. Interacts with UBQLN4 (via STI1 1 and 2 domains). Interacts
CC       with UBQLN1 in the presence of UBQLN4. Interacts with ATG13. Interacts
CC       with RETREG1, RETREG2 and RETREG3 (By similarity). Interacts with
CC       PLCL1; the interaction inhibits autophagosome formation
CC       (PubMed:23399561). Interacts with TRIM16. Interacts with CRY1 and PER2
CC       (PubMed:29937374). Interacts with the reticulophagy receptor TEX264 (By
CC       similarity). Membrane-bound form LC3-II interacts with PHB1 and PHB2;
CC       the interaction takes place upon Parkin-mediated mitochondrial damage
CC       (By similarity). Interacts with PJVK; the interaction is direct
CC       (PubMed:30936319). Interacts with KBTBD6 and KBTBD7; the interaction is
CC       direct (By similarity). Interacts with AMBRA1 (via LIR motif) (By
CC       similarity). Interacts with JMY; the interaction results in the
CC       activation of JYM's nucleation activity in the cytoplasm (By
CC       similarity). Interacts with MOAP1 (via LIR motif) (By similarity).

CC   -!- SUBCELLULAR LOCATION: Cytoplasmic vesicle, autophagosome membrane
CC       {ECO:0000269|PubMed:11266458, ECO:0000269|PubMed:12207896}; Lipid-
CC       anchor {ECO:0000250|UniProtKB:Q9GZQ8}. Endomembrane system

CC       {ECO:0000250|UniProtKB:Q9GZQ8}. Cytoplasm, cytoskeleton
CC       {ECO:0000305|PubMed:12207896}. Cytoplasmic vesicle
CC       {ECO:0000250|UniProtKB:Q9GZQ8}. Note=LC3-II binds to the autophagic
CC       membranes. LC3-II localizes with the mitochondrial inner membrane
CC       during Parkin-mediated mitophagy (By similarity). Localizes also to
CC       discrete punctae along the ciliary axoneme (By similarity).
CC       {ECO:0000250|UniProtKB:Q9GZQ8}.
CC   -!- PTM: The precursor molecule is cleaved by ATG4 (ATG4A, ATG4B, ATG4C or
CC       ATG4D) to expose the glycine at the C-terminus and form the cytosolic
CC       form, LC3-I (PubMed:12207896, PubMed:14530254). The processed form is
CC       then activated by APG7L/ATG7, transferred to ATG3 and conjugated to
CC       phosphatidylethanolamine (PE) phospholipid to form the membrane-bound
CC       form, LC3-II (By similarity). During non-canonical autophagy, the
CC       processed form is conjugated to phosphatidylserine (PS) phospholipid
CC       (By similarity). ATG4 proteins also mediate the delipidation of PE-
CC       conjugated forms (PubMed:33795848). In addition, ATG4B and ATG4D
CC       mediate delipidation of ATG8 proteins conjugated to PS during non-
CC       canonical autophagy (By similarity). ATG4B constitutes the major
CC       protein for proteolytic activation (By similarity). ATG4D is the main
CC       enzyme for delipidation activity (PubMed:33795848).
CC       {ECO:0000250|UniProtKB:Q9GZQ8, ECO:0000269|PubMed:12207896,
CC       ECO:0000269|PubMed:14530254, ECO:0000269|PubMed:33795848}.
CC   -!- PTM: Phosphorylation by PKA inhibits conjugation of
CC       phosphatidylethanolamine (PE). Interaction with MAPK15 reduces the
CC       inhibitory phosphorylation and increases autophagy activity.
CC       {ECO:0000250|UniProtKB:Q9GZQ8}.
CC   -!- SIMILARITY: Belongs to the ATG8 family. {ECO:0000305}.
