MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a receptor belonging to the Ig superfamily that is expressed on myeloid cells. This protein amplifies neutrophil and monocyte-mediated inflammatory responses triggered by bacterial and fungal infections by stimulating release of pro-inflammatory chemokines and cytokines, as well as increased surface expression of cell activation markers. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Jun 2011]
PHENOTYPE: Mice homozygous for a reporter allele exhibit decreased susceptibility to DEN induced tumors and liver damage. Mice homozygous for a knock-out allele of Trem1 and Trem3 exhibit increased susceptibility to P. aeruginosa infection with reduced neutrophil transepithelial migration. [provided by MGI curators]
