Biological function summary
LC3A participates in the formation of autophagosomes which are double-membraned vesicles that capture cellular waste for degradation. LC3A's conversion from LC3-I to LC3-II on the autophagosomal membrane signals the initiation of autophagy. It associates with proteins in the Atg family forming complexes that regulate the maturation of autophagosomes. The LC3 family including LC3A and LC3B acts as important components in the cell's ability to maintain homeostasis through autophagic activity.
Pathways
LC3A plays a vital part in the autophagy pathway and is also linked to the mTOR signaling pathway. Autophagy is a process that helps with the recycling of cellular components and mTOR signaling inhibits autophagy when nutrients are abundant. LC3A's interactions with other proteins such as p62 and ULK1 are essential in modulating these processes and ensuring cell survival under stress conditions. LC3A and LC3B's roles are integral in coordinating the cellular response to nutrient status and stress highlighting their importance in cellular regulation.

General info
Function
Ubiquitin-like modifier involved in formation of autophagosomal vacuoles (autophagosomes) (PubMed : 20713600, PubMed : 24290141). While LC3s are involved in elongation of the phagophore membrane, the GABARAP/GATE-16 subfamily is essential for a later stage in autophagosome maturation (PubMed : 20713600). Through its interaction with the reticulophagy receptor TEX264, participates in the remodeling of subdomains of the endoplasmic reticulum into autophagosomes upon nutrient stress, which then fuse with lysosomes for endoplasmic reticulum turnover (PubMed : 31006537, PubMed : 31006538).
Sequence similarities
Belongs to the ATG8 family.
Post-translational modifications
The precursor molecule is cleaved by ATG4 (ATG4A, ATG4B, ATG4C or ATG4D) to expose the glycine at the C-terminus and form the cytosolic form, LC3-I (PubMed:15187094, PubMed:30661429). The processed form is then activated by APG7L/ATG7, transferred to ATG3 and conjugated to phosphatidylethanolamine (PE) phospholipid to form the membrane-bound form, LC3-II (PubMed:15187094). During non-canonical autophagy, the processed form is conjugated to phosphatidylserine (PS) phospholipid (PubMed:33909989). ATG4 proteins also mediate the delipidation of PE-conjugated forms (PubMed:32686895, PubMed:33909989). In addition, ATG4B and ATG4D mediate delipidation of ATG8 proteins conjugated to PS during non-canonical autophagy (PubMed:33909989). ATG4B constitutes the major protein for proteolytic activation (PubMed:30661429, PubMed:33909989). ATG4D is the main enzyme for delipidation activity (By similarity).. (Microbial infection) The Legionella effector RavZ is a deconjugating enzyme that hydrolyzes the amide bond between the C-terminal glycine residue and an adjacent aromatic residue in ATG8 proteins conjugated to phosphatidylethanolamine (PE), producing an ATG8 protein that is resistant to reconjugation by the host machinery due to the cleavage of the reactive C-terminal glycine (PubMed:23112293, PubMed:31722778, PubMed:32686895). RavZ is also able to mediate delipidation of ATG8 proteins conjugated to phosphatidylserine (PS) (PubMed:33909989).. Phosphorylation at Ser-12 by PKA inhibits conjugation to phosphatidylethanolamine (PE).
