Verification Images

  • Experimental Validation Results for LC3A Antibody (YA5456)
    Western blot analysis was performed on protein extracts (25 μg) from Mouse brain (lane 2) and Rat brain (lane 3) using LC3A antibody. Proteins were transferred onto a 0.45 μm PVDF membrane using the Trans-Blot® Turbo™ system for 13 min. The membrane was then blocked with 5% nonfat milk in TBST (HY-K1025) for 1 h at room temperature. The primary antibody (1:1000) and loading control antibody GAPDH Antibody (HRP) (HY-P80954A) (1:5000) were diluted in 5% nonfat milk in TBST and incubated with the membrane overnight at 4°C. After washing, the membrane of primary antibody was incubated with HRP-conjugated goat anti-rabbit/mouse IgG secondary antibody (HY-P8001/HY-P8004) (1:5000) diluted in 5% nonfat milk in TBST for 1 h at room temperature. Protein bands were visualized using an Ultra High Sensitivity ECL detection kit (HY-K1005).

Background

  • Function

    LC3A is an Ubiquitin-like modifier involved in formation of autophagosomal vacuoles (autophagosomes). While LC3s are involved in elongation of the phagophore membrane, the GABARAP/GATE-16 subfamily is essential for a later stage in autophagosome maturation. 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[1][2][3][4].

  • Subcellular Localization

    Cytoplasmic vesicle, autophagosome membrane; Lipid-anchor; Endomembrane system; Lipid-anchor; Cytoplasm, cytoskeleton

  • Expression


    Tissue_specificity:It is most abundant in the heart, brain, liver, skeletal muscle and testes, but is not found in the thymus and peripheral blood leukocytes.

  • Isoforms & Post-Translational Modification

    Q9H492 has 2 isomers: Q9H492-1: 14272 Da (predicted); Q9H492-2: 14493 Da (predicted).
    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)

  • Subunit

    Interacts with TP53INP1 and TP53INP2 (PubMed:19056683, PubMed:22470510). Directly interacts with SQSTM1; this interaction leads to MAP1LC3A recruitment to inclusion bodies containing polyubiquitinated protein aggregates and to inclusion body degradation by autophagy (PubMed:17580304).
