GABARAPL1/GEC-1 Protein, Human (His)

GABARAPL1/GEC-1 is a multifunctional ubiquitin-like modifier that contributes to cell surface expression of kappa-type opioid receptors and contributes to autophagy, shaping autophagosome vacuoles. Unlike LC3, which is involved in phagophore elongation, the GABARAP/GATE-16 subfamily plays a crucial role in late autophagosome maturation. GABARAPL1/GEC-1 Protein, Human (His) is the recombinant human-derived GABARAPL1/GEC-1 protein, expressed by E. coli , with N-6*His labeled tag. The total length of GABARAPL1/GEC-1 Protein, Human (His) is 117 a.a., with molecular weight of ~20.0 kDa.

GABARAPL1/GEC-1, a ubiquitin-like modifier, plays a multifaceted role in cellular processes. It enhances the cell-surface expression of kappa-type opioid receptors by facilitating their anterograde intracellular trafficking. Additionally, GABARAPL1/GEC-1 contributes to autophagy, participating in the formation of autophagosomal vacuoles. While LC3s are associated with phagophore membrane elongation, the GABARAP/GATE-16 subfamily assumes a crucial role in later stages of autophagosome maturation. Furthermore, GABARAPL1/GEC-1 collaborates with the reticulophagy receptor TEX264 to remodel subdomains of the endoplasmic reticulum into autophagosomes during nutrient stress, facilitating subsequent fusion with lysosomes for endoplasmic reticulum turnover. The protein engages in a network of interactions with various partners, including ATG13, OPRK1, RB1CC1, ULK1, TP53INP1, TP53INP2, SQSTM1, ATG3, ATG7, MAP15, TECPR2, TBC1D5, MAPK15, TRIM5, MEFV, TRIM21, WDFY3, UBA5, KBTBD6, KBTBD7, RETREG1, RETREG2, RETREG3, TEX264, and IRGM, underscoring its significance in cellular homeostasis and autophagic processes.
