Detection of Human, Mouse, and Rat GATE-16 by Western Blot. Western blot shows lysates of K562 human chronic myelogenous leukemia cell line, mouse brain (cerebellum) tissue, and rat brain (total) tissue. PVDF membrane was probed with 2 µg/mL of Rat Anti-Human/Mouse/Rat GATE-16 Monoclonal Antibody (Catalog # MAB9035) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for GATE-16 at approximately 15 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Golgi-associated ATPase Enhancer of 16 kDa (GATE-16), also known as Apg8p2 and GABARAPL2, is a 117 amino acid (aa) polypeptide and a member of the Autophagy-related 8 (Atg8) family of proteins (1). GATE-16/Apg8p2 has 100% aa sequence identity with its mouse and rat orthologs, and is orthologous to the yeast Atg8. Atg8 family members show structural similarity with Ubiquitin, but lack aa sequence similarity. GATE-16/Apg8p2 is best known for its role in autophagy (2,3). GATE-16/Apg8p2 covalently attaches to phosphatidylethanolamine (PE) the phagophore (autophagosome precursor) membrane using a Ubiquitin-like conjugation system that includes Ubiquitin-activating (E1)-, Ubiquitin-conjugating (E2)-, and Ubiquitin Ligase (E3)-like enzymes. Here it is involved in the later stages of autophagosome formation (4,5). It may also be involved in cargo recruitment to autophagosomes (1).
