FunctionGBRAP_HUMAN May play a role in intracellular transport of GABA(A) receptors and its interaction with the cytoskeleton. Involved in apoptosis. Involved in autophagy (By similarity).[1] Publication Abstract from PubMedThe recruitment of Unc-51-like kinase and TANK-binding kinase 1 complexes is essential for Nuclear dot protein 52-mediated selective autophagy and relies on the specific association of NDP52, RB1-inducible coiled-coil protein 1, and Nak-associated protein 1 (5-azacytidine-induced protein 2, AZI2). However, the underlying molecular mechanism remains elusive. Here, we find that except for the NDP52 SKIP carboxyl homology (SKICH)/RB1CC1 coiled-coil interaction, the LC3-interacting region of NDP52 can directly interact with the RB1CC1 Claw domain, as that of NAP1 FIP200-binding region (FIR). The determined crystal structures of NDP52 SKICH/RB1CC1 complex, NAP1 FIR/RB1CC1 complex, and the related NAP1 FIR/Gamma-aminobutyric acid receptor-associated protein complex not only elucidate the molecular bases underpinning the interactions of RB1CC1 with NDP52 and NAP1 but also reveal that RB1CC1 Claw and Autophagy-related protein 8 family proteins are competitive in binding to NAP1 and NDP52.
