MERTK Antibody — Figure 4 Role of AXL and MER in MuV replication. (A) Expression of AXL and MER receptors. SC and LC were isolated from 3-week-old wide-type (WT), Axl knockout (Axl -/-), Mer knockout (Mer -/-), and Axl/Mer double knockout (Axl -/- Mer -/-) mice. The expression of AXL and MER was examined by Western blot. (B) MuV binding. SC and LC with the indicated genotypes were incubated with 100 MOI of MuV for 1 h on ice. MuV-NP RNA (upper panels) and protein (lower panels) levels were determined by real-time qRT-PCR and Western blot, respectively. (C) MuV internalization. SC and LC were incubated with 100 MOI of MuV for 1 h at 37°C. MuV-NP RNA (upper panels) and protein (lower panels) levels were determined. (D) MuV replication. SC and LC were infected with 1.0 MOI of MuV. MuV-NP RNA (upper panels) and protein (lower panels) levels were determined at 48 h after infection. (E) Intracellular MuV. WT and Axl -/- Mer -/- SC (left panels) and LC (right panels) were infected with MuV as described in (D). Intracellular MuV-NP (red) was localized by IF staining at 48 h. Cellular plasma and nuclei were visualized using IF for alpha-tubulin (green) and DAPI (blue) counterstaining, respectively. (F) MuV loads in culture medium. SC and LC were infected with MuV as described in (D). Virus loads in culture media were measured by TCID50 assay at 48 h after infection. (G) MuV replication in vivo, MuV (1 107 PFU) in 10 µL of PBS was injected into each testis of 8-week-old WT and Axl -/- Mer -/- mice (n=3 mice each group). Total RNA was extracted from the testis and relative RNA level of MuV-NP was {KO}

Product Specific Information

Description: This DS5MMER monoclonal antibody recognizes mouse MerTK, a 170-210 kDa member of the TAM family of tyrosine kinase receptors that also includes Axl and Tyro3. MerTK is expressed on tissue macrophages and is involved in the removal of apoptotic cells. This process relies on two soluble ligands of MerTK, Protein S and Gas6 that bind to phosphatidylserine found on the outer leaflet of the plasma membrane of cells undergoing apoptosis. Upon binding these ligands, MerTK undergoes autophosphorylation at multiple tyrosine residues that activate the PI3K and Akt pathways. This results in the phagocytosis of apoptotic cells and also results in the direct inhibition of TLR-induced production of pro-inflammatory cytokines. In addition, MerTK may function as a putative entry receptor for filoviruses. Deficiency of MerTK causes general autoimmunity, inflammation and accumulation of apoptotic bodies. MerTK is constitutively released from the cell surface by metalloproteinases and thus is present in the serum and culture medium. This process can be enhanced by stimulation with LPS. MerTK can be used to help discriminate macrophages from dendritic cells. MerTK is often expressed on malignant cells and may be implicated in immune evasion.

The DS5MMER antibody will work on paraformaldehyde-fixed cells. In addition, this antibody was demonstrated to inhibit Gas6-induced MerTK phosphorylation with the IC50 < 5 nM. The DS5MMER antibody also works in western blotting and immunoprecipitation.

Applications Reported: This DS5MMER antibody has been reported for use in flow cytometric analysis, immunohistochemical staining, immunohistochemical staining of frozen tissue sections, western blotting and immunoprecipitation. Fluorochrome-conjugated DS5MMER is recommended for use in flow cytometry.

Applications Tested: This DS5MMER antibody has been tested by immunohistochemistry on frozen mouse tissue and can be used at less than or equal to 5 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

Purity: Greater than 90%, as determined by SDS-PAGE.

Aggregation: Less than 10%, as determined by HPLC.

Filtration: 0.2 µm post-manufacturing filtered.

Target Information

MERTK (cMER) is a tyrosine kinase proto-oncogene and is involved in the retinal pigment epithelium (RPE) phagocytosis pathway, which is implicated in human retinal disease. Regulates many physiological processes including cell survival, migration, differentiation, and phagocytosis of apoptotic cells (efferocytosis). Ligand binding at the cell surface induces autophosphorylation of MERTK on its intracellular domain that provides docking sites for downstream signaling molecules. Following activation by ligand, interacts with GRB2 or PLCG2 and induces phosphorylation of MAPK1, MAPK2, FAK/PTK2 or RAC1. MERTK signaling plays a role in various processes such as macrophage clearance of apoptotic cells, platelet aggregation, cytoskeleton reorganization and engulfment. Functions in the retinal pigment epithelium (RPE) as a regulator of rod outer segments fragments phagocytosis. Plays also an important role in inhibition of Toll-like receptors (TLRs)-mediated innate immune response by activating STAT1, which selectively induces production of suppressors of cytokine signaling SOCS1 and SOCS3.
