Trem-like transcript 4 protein (Treml4)

Positively regulates Toll-like receptor signaling through TLR7, TLR9 and TLR13 in neutrophils and splenic macrophages (PubMed:25848864). Regulates TLR7 signaling by controlling ligand- induced recruitment of TLR7 in the endoplasmic reticulum into endosomes and lysosomes (PubMed:25848864).

Positively regulates Toll-like receptor TLR9-induced production of inflammatory cytokines but is dispensable for IFNB1 production (PubMed:25848864). Involved in the anti-viral reaction to many viruses including influenza virus, vesicular stomatitis virus and cytomegalovirus (PubMed:25848864).
