      Background InformationMicrotubule-associated proteins 1A/1B light chain 3B (UniProt: Q9GZQ8; also known as Autophagy-related protein LC3B, Autophagy-related ubiquitin-like modifier LC3B, MAP1 light chain 3-like protein 2, MAP1A/MAP1B light chain 3 B, MAP1A/MAP1B LC3B, Microtubule-associated protein 1 light chain 3 beta) is encoded by the MAP1LC3B (also known as MAP1ALC3) gene (Gene ID: 81631) in human. LC3 is ubiquitously distributed in all eukaryotes and is expressed as three splice variants known as LC3A, LC3B, and LC3C. They are structural proteins of autophagosomal membranes and are widely used as biomarkers of autophagy. They are ubiquitously distributed in all eukaryotes. They possess a ubiquitin-like structure despite differences in their respective amino acid sequences. The amino-terminus of LC3 is composed of an alpha-helix that varies among the 3 members. However, its C-terminus is conserved and consists of a ubiquitin core composed of beta strands with hydrophobic pockets. The ubiquitin core region is responsible for its interaction with Atg core machinery proteins. LC3 is cleaved by Atg4 between amino acids 120-121 to form LC3-I and expose its C-terminal glycine. LC3-I then conjugates to phosphatidylethanolamine (PE) by Atg7, Atg3, and the Atg12 complex to generate LC3-II, which is inserted into autophagosome membrane. LC3B is reported to be most abundant in heart, brain, skeletal muscle and testis and only a trivial expression is observed in the liver. Higher expression of LC3B in triple negative breast cancer is associated with poor outcomes in patients. It plays a role in mitophagy and regulates mitochondrial quantity and quality by eliminating the mitochondria to a basal level to fulfill cellular energy requirements and preventing excess reactive oxygen species production. C3B is synthesized with a propeptide (aa 121-125), which is cleaved off to produce the mature form. LC3B can undergo phosphorylation at threonine 12 by protein kinase A (PKA) and this phosphorylation inhibits its conjugation to phosphatidylethanolamine. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
