Predicted to enable receptor decoy activity; scaffold protein binding activity; and transmembrane signaling receptor activity. Acts upstream of or within neutrophil chemotaxis; neutrophil extravasation; and neutrophil-mediated killing of gram-negative bacterium. Predicted to be located in plasma membrane. Predicted to be active in cell surface and extracellular space. Is expressed in bladder and renal vasculature. Human ortholog(s) of this gene implicated in bacterial pneumonia; bacterial sepsis; malaria; and myocardial infarction. Orthologous to human TREM1 (triggering receptor expressed on myeloid cells 1).
MGI Description
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]
