Description: Autophagy is a process of intracellular bulk degradation in which cytoplasmiccomponents, including organelles, are sequestered within double-membrane vesiclesthat deliver the contents to the lysosome/vacuole for degradation. Duringmacroautophagy, the sequestering vesicles, termed autophagosomes, fuse with thelysosome or vacuole resulting in the delivery of an inner vesicle (autophagic body) intothe lumen of the degradative compartment. There are 16 proteins participating in theautophagy pathway in human. The autophagy protein LC3, a mammalian homologue ofAtg8, was originally identified as microtubule-associated protein 1 light chain 3. It is acomponent of both the MAP1A and MAP1B microtubule-binding domains and theheavy-chain independent regulation of LC3 expression might modify MAP1microtubule-binding activity during development. LC3 is the only known mammalianprotein identified that stably associates with the autophagosome membranes. LC3-I iscytosolic and LC3-II is membrane bound and enriched in the autophagic vacuolefraction. The detection of LC3-I to LC3-II conversion is a useful and sensitive marker fordistinguishing autophagy in mammalian cells. Alternate Names: anti-Microtubule-associated proteins 1A/1B light chain 3B MAP1A/MAP1B LC3 Bantibody, anti-MAP1A/b light chain 3 B antibody, anti-Autophagy-related protein LC3 Bantibody, anti-Autophagy-related ubiquitin-like modifier LC3 B antibody.

Specificity: Species Reactivity: Reacts with human,mouse, rat, Xenopus and Bovine. Localization: LC3-I is cytoplasmic. LC3-II binds to the autophagic membranes.
