Background: Mer

Tyrosine-protein Kinase Mer, also known as c-Mer and MerTK, is a member of the receptor tyrosine kinase subfamily TAM (Tyro3, Axl, and Mer). Mature cynomolgus Mer consists of 484 amino acid (aa) extracellular domain (ECD), a 20 aa transmembrane segment, and a 472 aa cytoplasmic domain. Within the ECD, cynomolgus Mer shares 95% and 99% sequence identity with human and rhesus monkey, respectively. Similar to Axl and Tyro3, the ECD of Mer contains two Ig-like motifs and two fibronectin type III motifs. Mer is not expressed in normal B- and T-cells but is expressed in neoplastic B- and T-cell lines (1-2).  It also shows higher expression in immunosuppressive M2‑like macrophages (3).  Mer is known to bind Gas6, Protein S, Tubby, Tubby-like protein 1 (Tulp1), and Galectin-3 (4-7). Binding of Gas6 lead to cell proliferation, migration or the prevention of apoptosis. Upon binding ligands via the Ig-like motif, Mer is dimerized to trans-autophosphorylate the kinase domain to induce downstream signaling. It has been shown that Mer signaling in macrophages induces M2 polarization, which promotes tumor growth, metastasis and evasion of anti-tumor immunity in tumor microenviroment (8). Inhibition of Mer, especially on leukocytes and macrophages, is an effective anti-cancer therapy (9).
