Application Abreviews Notes
Flow Cyt Use at an assay dependent concentration.
WB 1/1000 - 1/10000. Predicted molecular weight: 14 kDa.
IHC-P 1/500 - 1/1000. Antigen retriecal is recommended
ICC/IF 1/100 - 1/500.
  • Application notesIs unsuitable for IP.
  • Target

    • FunctionUbiquitin-like modifier that plays a role in intracellular transport of GABA(A) receptors and its interaction with the cytoskeleton. Involved in apoptosis. Involved in autophagy. Whereas LC3s are involved in elongation of the phagophore membrane, the GABARAP/GATE-16 subfamily is essential for a later stage in autophagosome maturation.
    • Tissue specificityHeart, brain, placenta, liver, skeletal muscle, kidney and pancreas.
    • Sequence similaritiesBelongs to the ATG8 family.
    • Post-translational
      The precursor molecule is cleaved by ATG4B to form the cytosolic form, GABARAP-I. This is activated by APG7L/ATG7, transferred to ATG3 and conjugated to phospholipid to form the membrane-bound form, GABARAP-II.
    • Cellular localizationEndomembrane system. Cytoplasm, cytoskeleton. Golgi apparatus membrane. Cytoplasmic vesicle, autophagosome. Largely associated with intracellular membrane structures including the Golgi apparatus and postsynaptic cisternae. Colocalizes with microtubules (By similarity). Localizes also to discrete punctae along the ciliary axoneme (By similarity).

    • ab109364 staining GABARAP in the human cell line HeLa (human cervix adenocarcinoma) by flow cytometry. Cells were fixed with 4% paraformaldehyde, permiabilised with 90% methanol and the sample was incubated with the primary antibody at a dilution of 1/20. A goat anti rabbit IgG (Alexa Fluor® 488) at a dilution of 1/2000 was used as the secondary antibody.
