Predicted to enable scaffold protein binding 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 integral component of membrane. 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).
