Protein Information (annotations from UniProt)

Database IDHIV0001124
UniProt IDQ9H0R8
Primary gene name(s)GABARAPL1
Synonym gene name(s)GEC1
Protein nameGamma-aminobutyric acid receptor-associated protein-like 1
Protein functionUbiquitin-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. {ECO:0000269|PubMed:16431922, ECO:0000269|PubMed:20404487}.
Subcellular locationCytoplasm, cytoskeleton. Cytoplasmic vesicle membrane;
Lipid-anchor. Endoplasmic reticulum {ECO:0000250}. Golgi apparatus {ECO:0000250}. Cytoplasmic vesicle, autophagosome.
