Scientific Data Images for Human GABARAP Antibody

Detection of Human and Mouse GABARAP antibody by Western Blot.

Detection of Human and Mouse GABARAP by Western Blot.

Western blot shows lysates of A172 human glioblastoma cell line and NIH-3T3 mouse embryonic fibroblast cell line untreated (-) or treated (+) with 50 µM Chloroquine for 20 hours. PVDF membrane was probed with 2 µg/mL of Rat Anti-Human GABARAP Monoclonal Antibody (Catalog # MAB8574) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). Specific bands were detected for GABARAP at approximately 14 & 16 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 7.
GABARAP antibody in A172 Human Cell Line by Immunocytochemistry (ICC).

GABARAP in A172 Human Cell Line.

GABARAP was detected in immersion fixed A172 human glioblastoma cell line using Rat Anti-Human GABARAP Monoclonal Antibody (Catalog # MAB8574) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to Golgi apparatus and cytoplasmic vesicles. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: GABARAP

gamma-Aminobutyric Acid Receptor-associated Protein (GABARAP), also known as Apg8p1, is 117 amino acid (aa) protein with a predicted molecular weight of 14 kDa. It is a member of the GABARAP subfamily of the Autophagy-related 8 (Atg8) family of proteins (1). The GABARAP subfamily also includes GABARAPL1. GABARAP/Apg8p1 has 100% aa sequence identity with its mouse and rat orthologs and is orthologous to yeast Atg8. Atg8 family members show structural similarity with Ubiquitin, but lack aa sequence similarity. GABARAP/Apg8p1 was first described for its putative involvement GABA A Receptor trafficking (2,3). However, it is best known for its role in autophagy (1,4). GABARAP/Apg8p1 covalently attaches to phosphatidylethanolamine (PE) in 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 maturation (4,5). It may also be involved in cargo recruitment to autophagosomes (1).
