Proline-rich protein 7 (PRR7)

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 (PubMed:27458189).

Might play a redundant role in the regulation of T cell receptor signaling (PubMed:21460222). Might encourage apoptosis in T cells (PubMed:21460222).
