DESCRIPTION

Also known as GRIP1_RAT, Grip1. May play a role as a localized scaffold for the assembly of a multiprotein signaling complex and as mediator of the trafficking of its binding partners at specific subcellular location in neurons (PubMed:9069286). Through complex formation with NSG1, GRIA2 and STX12 controls the intracellular fate of AMPAR and the endosomal sorting of the GRIA2 subunit toward recycling and membrane targeting (PubMed:16037816). Interacts with EFNB1, EPHA7, EPHB2, EFNB3, KIF5A, KIF5C, KIF5B and the C-terminal tail of PRLHR. Forms a ternary complex with GRIA2 and CSPG4 (By similarity). Can form homomultimers or heteromultimers with GRIP2. Interacts with GRIA2, GRIA3, GRIPAP1/GRASP1, PPFIA1, PPFIA4, FRAS1, PLCD4, PTPRF and liprins-alpha. Interacts with ATAD1 in an ATP-dependent manner. ATAD1-catalyzed ATP hydrolysis disrupts binding to ATAD1 and to GRIA2 and leads to AMPAR complex disassembly. Interacts with SLC30A9 (By similarity). Interacts with BUD23 (By similarity). Forms a complex with NSG1, GRIA2 and STX12; controls the intracellular fate of AMPAR and the endosomal sorting of the GRIA2 subunit toward recycling and membrane targeting (PubMed:16037816). Interacts with NSG1 (PubMed:16037816).
