General description

Anti-PLA2R antibody, Mouse monoclonal (mouse IgG2b isotype) is derived from the 12-6-5 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from mice immunized with recombinant fragment of human PLA2R corresponding to extracellular sequence NC3. Secretory phospholipase A2 receptor (PLA2R) is 180 kDa and is a type I transmembrane glycoprotein member of the mannose receptor (MR) family. Large extracellular glycosylated region comprising an N-terminal cysteine-rich domain (CysR), a fibronectin-like type II domain (FnII), and eight to ten C-type lectin-like domains (CTLD).

Immunogen

Human PLA2R extracellular sequence N-C3 (containing domains N-terminal Cysteine rich-FibII-CTLD1-CTLD2-CTLD3)

Application

Anti-PLA2R antibody has been used in
  • immunoblotting
  • immunofluorescence
  • flow Cytometry
  • immunohistochemistry

Biochem/physiol Actions

Secretory phospholipase A2 receptor (PLA2R) acts as a receptor for secretory phosholipase A2 (sPLA2) allowing its removal from circulation, thus regulating its biological effect. PLA2R is also involved in clearance followed by suppression of their potent enzymatic activities of secretory phospholipase A2 (sPLA2) from the blood, including group sPLA2-X and a snake venom sPLA2. The soluble circulating form of PLA2R is constitutively present as an endogenous inhibitor of sPLA2s. PLA2R is expressed in kidney podocytes of normal human glomeruli, in idiopathic membranous nephropathy (IMN) patients PLA2R is colocalized to immune deposits in glomeruli along with IgG4.
