Negatively regulates microglial inflammatory responses (PubMed:38892217). Inhibits NF-kappa-B signaling by interacting with PRMT2, thereby reducing the production of pro-inflammatory cytokines, maintaining a steady-state in microglia and limiting excessive inflammation (PubMed:38892217). . This is the function of ENSG00000167173 (PRMT2IP, PRMT2 interacting protein).
