Anti-Autophagy-Related Protein 4 Homolog B (APG4B) Antibody

FUNCTION: Cysteine protease required for autophagy, which cleaves the C-terminal part of either MAP1LC3, GABARAPL2 or GABARAP, allowing the liberation of form I. A subpopulation of form I is subsequently converted to a smaller form (form II) . Form II, with a revealed C-terminal glycine, is considered to be the phosphatidylethanolamine (PE) -conjugated form, and has the capacity for the binding to autophagosomes. ENZYME REGULATION: Inhibited by N-ethylmaleimide. SUBCELLULAR LOCATION: Cytoplasm (Probable) . ALTERNATIVE PRODUCTS: 5 named isoforms produced by alternative splicing. TISSUE SPECIFICITY: Mainly expressed in the skeletal muscle, followed by brain, heart, liver and pancreas. SIMILARITY: Belongs to the peptidase C54 family.

Our Anti-Autophagy-related protein 4 homolog B (APG4B) rabbit polyclonal primary antibody detects human and rat Autophagy-related protein 4 homolog B (APG4B), and is whole serum. It is validated for use in IHC-Frozen, WB.

A synthetic peptide (CLERFFDSEDED) corresponding to the C-terminus of human ATG4B protein conjugated to Blue Carrier Protein has been used as the immunogen. The peptide is homologous with the corresponding sequence derived from of ATG4B protein in mouse and rat.

Spin vial briefly before opening. Reconstitute in 100 μL sterile-filtered, ultrapure water. Centrifuge to remove any insoluble material. After reconstitution keep aliquots at -20°C for a higher stability, and at 2-8°C with an appropriate antibacterial agent. Glycerol (1:1) may be added for an additional stability. Avoid repetitive freeze/thaw cycles.
