  • Function
    Ubiquitin-like modifier that increases cell-surface expression of kappa-type opioid receptor through facilitating anterograde intracellular trafficking of the receptor. Involved in formation of autophagosomal vacuoles. 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 specificity
    Ubiquitous. Expressed at very high levels in the brain, heart, peripheral blood leukocytes, liver, kidney, placenta and skeletal muscle. Expressed at very low levels in thymus and small intestine. In the brain, expression is particularly intense in motoneurons in the embryo and in neurons involved in somatomotor and neuroendocrine functions in the adult, particularly in the substantia nigra pars compacta.
  • Sequence similarities
    Belongs to the ATG8 family.
  • Post-translational
    The precursor molecule is cleaved by ATG4B to form the cytosolic form, GABARAPL1-I. This is activated by APG7L/ATG7, transferred to ATG3 and conjugated to phospholipid to form the membrane-bound form, GABARAPL1-II (By similarity). ATG4B also mediates the delipidation required for GABARAPL1 recycling when autophagosomes fuse with lysosomes.
    The Legionella effector RavZ is a deconjugating enzyme that produces an ATG8 product that would be resistant to reconjugation by the host machinery due to the cleavage of the reactive C-terminal glycine.

  • Immunohistochemistry analysis of formalin-fixed,paraffin-embedded Human brain tissue labeling GABARAPL1 with ab94996 at 1/50 dilution which was peroxidase-conjugated to the secondary antibody,followed by DAB staining.

  • Flow cytometric analysis of Hela cells (right histogram) compared to a negative control cell (left histogram).FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.

Ab94996 has been produced with as immungen the whole molecule. The GABARAPL1 protein has 86% identity with the GABARAP protein. It is therefore difficult to make a prediction. Unfortunately, this antibody has not been tested by the laboratory for its c...
