Monocyte/macrophage- and neutrophil-mediated inflammatory responses can be stimulated through a variety of receptors, including G protein-linked 7-transmembrane receptors (e.g., FPR1; MIM 136537), Fc receptors (see MIM 146790), CD14 (MIM 158120) and Toll-like receptors (e.g., TLR4; MIM 603030), and cytokine receptors (e.g., IFNGR1; MIM 107470). Engagement of these receptors can also prime myeloid cells to respond to other stimuli. Myeloid cells express receptors belonging to the Ig superfamily, such as TREM1, or to the C-type lectin superfamily. Depending on their transmembrane and cytoplasmic sequence structure, these receptors have either activating (e.g., KIR2DS1; MIM 604952) or inhibitory functions (e.g., KIR2DL1; MIM 604936).[supplied by OMIM
Immunogen
TREM1 (NP_061113.1, 1 a.a. ~ 234 a.a) full-length human protein.
Triggering receptor expressed on myeloid cells like-1 (TREML1) associates with a transmembrane adaptor molecule called DNAX activation protein of 12kDa (DAP12). TREM1 induces calcium mobilization and triggers secretion of pro-inflammatory chemokines and cytokines.
Physical form
Solution in phosphate buffered saline, pH 7.4

We have identified new activating receptors of the Ig superfamily expressed on human myeloid cells, called TREM (triggering receptor expressed on myeloid cells). TREM-1 is selectively expressed on blood neutrophils and a subset of monocytes and is up-regulated by bacterial
