This A3KCAT antibody recognizes human MerTK, known also as MER or c-mer, a 170-210 kDa member of the TAM family of tyrosine kinase receptors that also includes Axl and Tyro3. MerTK is expressed on a subset of anti-inflammatory macrophages and is involved in the removal of apoptotic cells. This process relies on two soluble ligands of MerTK, Protein S and Gas6, that coat the surface 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 target cells and also the direct inhibition of TLR-induced production of pro-inflammatory cytokines by the phagocytes. MerTK may also function as a putative entry receptor for filoviruses. Deficiency of MerTK causes general autoimmunity, inflammation, and accumulation of apoptotic bodies. MerTK can be released from the cell surface by metalloproteinases, and this process is significantly enhanced when macrophages are stimulated e.g. with LPS. MerTK is often expressed on malignant cells, and may be implicated in immune evasion.
This A3KCAT antibody has been tested by immunohistochemistry of formalin-fixed paraffin embedded tissue using low or high pH antigen retrieval and can be used at less than or equal to 0.5 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.
This gene is a member of the MER/AXL/TYRO3 receptor kinase family and encodes a transmembrane protein with two fibronectin type-III domains, two Ig-like C2-type (immunoglobulin-like) domains, and one tyrosine kinase domain. Mutations in this gene have been associated with disruption of the retinal pigment epithelium (RPE) phagocytosis pathway and onset of autosomal recessive retinitis pigmentosa (RP).
