CC -!- FUNCTION: Plays a role in the recycling mechanism in neurons of
CC multiple receptors, including AMPAR, APP and L1CAM and acts at the
CC level of early endosomes to promote sorting of receptors toward a
CC recycling pathway. Regulates sorting and recycling of GRIA2 through
CC interaction with GRIP1 and then contributes to the regulation of
CC synaptic transmission and plasticity by affecting the recycling and
CC targeting of AMPA receptors to the synapse (By similarity). Is required
CC for faithful sorting of L1CAM to axons by facilitating trafficking from
CC somatodendritic early endosome or the recycling endosome (By
CC similarity). In an other hand, induces apoptosis via the activation of
CC CASP3 in response to DNA damage (By similarity).

CC ECO:0000250|UniProtKB:Q62092}.
CC -!- SUBUNIT: Forms a complex with GRIP1, GRIA2 and STX12 through direct
CC interaction with GRIP1; controls the intracellular fate of AMPAR and
CC the endosomal sorting of the GRIA2 subunit toward recycling and
CC membrane targeting. Interacts with STX12 (By similarity). Interacts
CC with APP; could regulate APP processing (By similarity). Interacts with
CC FAM171A1 (By similarity). {ECO:0000250|UniProtKB:P02683,

CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:P02683}; Single-
CC pass type II membrane protein {ECO:0000250|UniProtKB:P02683}. Golgi
CC apparatus, trans-Golgi network membrane {ECO:0000250|UniProtKB:P02683}.

CC {ECO:0000250|UniProtKB:P02683}. Cytoplasmic vesicle membrane
CC {ECO:0000250|UniProtKB:P02683}. Golgi apparatus, Golgi stack membrane
CC {ECO:0000250|UniProtKB:P02683}. Endosome, multivesicular body membrane
CC {ECO:0000250|UniProtKB:P02683}. Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:P42857}. Note=Endocytosed from the cell surface,
CC thus enters into early endosomes, trafficks to late endosomes and
CC degradates in lysosomes (By similarity). Endoplasmic reticulum
CC targeting is essential for apoptosis (By similarity). Found in both
CC stationary and motile endosomes. A previous study supports a type I
CC membrane protein topology (By similarity).

CC -!- SIMILARITY: Belongs to the NSG family. {ECO:0000305}.
