General description

LC3A is composed of a heavy chain and multiple light-chain subunits. The molecular machinery required for autophagy is highly conserved in all eukaryotes as seen by the high degree of conservation of proteins involved in the formation of the autophagosome membranes. Recently, both yeast Apg8p and its rat homologue LC3-II were identified as essential constituents of autophagosome membrane as a processed form. In addition, both the yeast and human proteins exist in two modified forms produced by a series of post-translational modifications including a critical C-terminal cleavage after a conserved Gly residue, and the smaller processed form is associated with the autophagosome membranes Results revealed different regulation of the three human isoforms of LC3-II and implicate that the three isoforms may have different physiological functions. Two forms of LC3A, called LC3-I and -II, were produced post-translationally in various cells. LC3-I is cytosolic, whereas LC3-II is membrane bound.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Target description

~16 kDa observed. LC3 can occur as a doublet around ~15 kDa, indicating the presence of both LC3-I & LC3-II. An uncharacterized band may appear at ~39 and ~55 kDa in some lysates.
