Function

Ubiquitin-like modifier that plays a role in intracellular transport of GABA(A) receptors and its interaction with the cytoskeleton (PubMed:9892355). Involved in autophagy: while LC3s are involved in elongation of the phagophore membrane, the GABARAP/GATE-16 subfamily is essential for a later stage in autophagosome maturation (PubMed:15169837, PubMed:20562859, PubMed:22948227). Through its interaction with the reticulophagy receptor TEX264, participates in the remodeling of subdomains of the endoplasmic reticulum into autophagosomes upon nutrient stress, which then fuse with lysosomes for endoplasmic reticulum turnover (PubMed:31006538). Also required for the local activation of the CUL3(KBTBD6/7) E3 ubiquitin ligase complex, regulating ubiquitination and degradation of TIAM1, a guanyl-nucleotide exchange factor (GEF) that activates RAC1 and downstream signal transduction (PubMed:25684205). Thereby, regulates different biological processes including the organization of the cytoskeleton, cell migration and proliferation (PubMed:25684205). Involved in apoptosis (PubMed:15977068). {PubMed:15169837, PubMed:15977068, PubMed:20562859, PubMed:22948227, PubMed:25684205, PubMed:31006538, PubMed:9892355}.

Target Background

Type-A receptors for the neurotransmitter GABA (gamma- aminobutyric acid) are ligand-gated chloride channels that mediate inhibitory neurotransmission. A cellular protein, GABA(A)-receptor associated protein (GABARAP), that interacts with the gamma 2 subunit of GABA(A) receptors and modulates receptor channel kinetics was recently identified. GABARAP binds to GABA(A) receptors in vitro and in vivo. Sequence analysis shows similarity between GABARAP and light chain-3 of microtubule-associated proteins 1A and 1B. The interactions between GABA(A) receptors, GABARAP and tubulin suggest a mechanism for the targeting and clustering of GABA(A) receptors.
