Western Blot: LC3A Antibody - BSA Free [NB100-2331] - LC3A Antibody [NB100-2331] - High autophagosome concentration is consumed during early immortalized human mesenchymal stem cell differentiation. Immortalized human mesenchymal stem cells were differentiated under osteogenic conditions (see Materials and methods) and assayed for changes in LC3I and LC3II during a 72-hour window. Cells were differentiated under standard conditions (top) or with addition of 5 uM rapamycin (middle) or 5 nM bafilomycin (bottom) for the first 3 hours of differentiation to modulate autophagy. Immunoblots were performed for LC3 at the indicated time points to assess autophagosome degradation via relative changes in LC3II (lower band; 17 kDa). Studies were repeated three times with similar trends seen consistently.

Application Notes
Western blot bands are seen at ~19 kDa, representing LC3-I, and ~17 kDa, representing LC3-II. The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors. Use in Southern blot reported in scientific literature (PMID: 21262964). In ICC, cytoplasmic staining was observed in HeLa cells. In Simple Western only 10 - 15 uL of the recommended dilution is used per data point.

Background: LC3A

Human Microtubule-associated Protein 1A/1B Light Chain 3A (MAP1LC3A), also called LC3A for short, is a 121 amino acid (aa) protein with a theoretic molecular weight of ~14 kDa. LC3A belongs to the LC3 subfamily of Autophagy-related 8 (Atg8) proteins, which also includes LC3B and LC3C (1). The process of autophagy is the bulk degradation of proteins and organelles. Whether these three proteins have distinct roles in autophagy remains unclear, but they do have unique subcellular expression (2). Specifically, LC3A shows perinuclear and nuclear localization (2). The Atg8 family members share a similar structure of two amino-terminal alpha-helices and a ubiquitin-like core but are unique in aa sequence (1). LC3 utilizes a ubiquitin-like conjugation system to covalently bind to phosphatidylethanolamine (PE), also called lipidation, which is mediated by a series of steps (1, 3). Briefly, unprocessed, cytosolic LC3 (pro-LC3) is cleaved by the cysteine protease Atg4 to expose a c-terminal glycine (Gly) residue (LC3-I); the Gly is activated by E1-like enzyme Atg7, transferred to E2-like enzyme Atg3, and an E3-like complex facilitates the conjugation of LC3 with PE (LC3-II), incorporating it into the phagophore membrane during autophagosome formation (1, 3). The recruitment of LC3 to the phagophore is thought to mediate membrane elongation and closure (1, 3). Additionally, LC3 plays a role in recruiting cargo (protein aggregates, pathogens, and organelles) to autophagosomes and delivery for lysosomal degradation (1).

The process of autophagy is associated with a variety of diseases including neurodegenerative diseases, neuromuscular, tumorigenesis, and viral and bacterial infections (4). LC3 is a useful marker of autophagy in both healthy and diseased cells (4). Interestingly, LC3A has two variants (v1 and v2) which differ in N-terminal sequence due to the varying transcriptional start sites (5). One particular study found that LC3Av1, but not v2 or LC3B, was silenced in various cancer cell lines due to aberrant DNA methylation and re-expression of LC3Av1 in LC3Av1-silenced cells inhibited tumor growth, where overall findings suggest a possible tumor-suppressive role (5).

Alternative names for LC3A include Apg8, APG8a, ATG8E, Autophagy-related protein LC3 A, Autophagy-related ubiquitin-like modifier LC3 A, MAP1A/1B light chain 3 A, microtubule-associated proteins 1A/1B light chain 3, and MLP3A.
