Background: TREML1/TLT-1

Triggering receptor expressed on myeloid cells-like protein 1 (TREML1)/TREM-like transcript-1 (TLT‑1) is a 40 kDa type I transmembrane receptor and member of the TREM family of proteins (1). Mouse TREML1/TLT-1 is synthesized as a 317 amino acid (aa) precursor that contains a 20 aa signal sequence, a 155 aa extracellular domain (ECD), a 21 aa transmembrane region, and a 121 aa cytoplasmic domain (SwissProt #: Q8K558). The ECD contains an Ig-like V-type domain (aa 21‑122), and the cytoplasmic region contains a proline-rich region (aa 245‑275) and an immunoreceptor tyrosine-based inhibition motif (ITIM) characterized by the residues S/I/V/LXYXXV/L (1). A splicing variant produces a second isoform that has a six aa substitution for aa 173 in isoform 1. Mature mouse TREML1/TLT-1 shares 65% aa sequence identity with mature human TREML1/TLT-1. TREML1/TLT-1 is expressed exclusively in megakaryocytes and platelets where it colocalizes with CD62P in alpha‑granules in resting platelets and on the cell surface of platelets activated by thrombin (1‑3). The receptor’s expression is up‑regulated dramatically upon platelet activation (2). Antibodies to single-chain Fv fragments specific for TLT-1 inhibited thrombin-mediated human platelet aggregation suggesting its role in the regulation of aggregation (5). In addition, soluble fragments including the ECD can be released into serum by proteolysis (3). The phosphorylated TREML1/TLT-1 is able to interact with both SHP-1 and SHP-2 through ITIM (1, 4). SHP-2 interaction enhances Fc epsilonRI-mediated calcium signaling in rat basophilic leukemia cells (1). It is hypothesized that TREML1/TLT-1 plays a role in the innate and adaptive immune responses.
