ID  Q3V0I2;
PN  Proline-rich protein 7;
GN  Prr7;
OS  10090;
SL  Nucleus Position: SL-0198;
SL  Comments: Cell membrane {ECO:0000250|UniProtKB:Q8TB68}; Single-pass type III membrane protein {ECO:0000305}. Postsynaptic cell membrane {ECO:0000250|UniProtKB:P0C6T3}; Single-pass type III membrane protein {ECO:0000305}. Postsynaptic density membrane {ECO:0000250|UniProtKB:P0C6T3}. Cytoplasm, perinuclear region {ECO:0000250|UniProtKB:Q8TB68}. Synapse {ECO:0000250|UniProtKB:P0C6T3}. Cell projection, dendrite {ECO:0000250|UniProtKB:P0C6T3}. Nucleus {ECO:0000250|UniProtKB:P0C6T3}. Note=Enriched in postsynaptic plasma membrane and postsynaptic densities (PSD). Accumulates in spines along with synapse maturation and colocalizes with DLG4 in a punctate pattern. Translocates from synapses to nuclei following NMDA receptor activity (By similarity). {ECO:0000250|UniProtKB:P0C6T3}.
DR  UNIPROT: Q3V0I2;
DE  Function: Acts as a synapse-to-nucleus messenger to promote NMDA receptor-mediated excitotoxicity in neurons in a JUN-dependent manner (By similarity). Inhibits ubiquitination-mediated degradation and promotes phosphorylation and transcriptional activity of transcription factor JUN (By similarity). Might play a redundant role in the regulation of T cell receptor signaling (PubMed:27657535). Might promote apoptosis in T cells (By similarity). {ECO:0000250|UniProtKB:P0C6T3, ECO:0000250|UniProtKB:Q8TB68, ECO:0000269|PubMed:27657535}.
