ANTI-PLA2R CLONE 5F5.1

General description

Secretory phospholipase A2 receptor (UniProt Q13018; also known as 180 kDa secretory phospholipase A2 receptor, C-type lectin domain family 13 member C, M-type receptor, Phospholipase A2 receptor 1) is encoded by the PLA2R1 (also known as CLEC13C, PLA2G1R, PLA2R, PLA2IR) gene (Gene ID 22925) in human. PLA2R is initially produced with a signal peptide sequence (a.a. 1-20), the cleavage of which yields the mature type I transmembrane receptor composed of a short cytoplasmic tail (a.a. 1419-1463), a transmembrane segment (a.a. 1419-1463), and a large extracellular portion consisting of an N-terminal cystein-rich region, a fibronectin-like type II domain, and a tandem repeat of eight carbohydrate-recognition domains (CRDs). Both group IB and X secretory phospholipase A2 (sPLA2) enzymes are identified as ligands orf PLA2R, while group IIA sPLA2s bind PLA2R with about 10-fold lower affinity when compared with group IB and X sPLA2s. In mice, the extracellular portion of PLA2R is reported to be cleaved off into a soluble form (sPLA2R) in blood, where it functions as a circulating sPLA2 inhibitory protein (PLI) that blocks both the receptor-binding and enzymatic activity of sPLA2.

Specificity

Expected to react with both spliced isoforms, as well as the soluble receptor (sPLA2R) derived from metalloproteinases-mediated cleavage of the membrane-bound receptor.

Immunogen

Epitope: Extracellular C-type lectin domains 3-5

GST-tagged recombinant protein corresponding to the extracellular C-type lectin domains 3-5 of human PLA2R.

Application

This Anti-PLA2R Antibody, clone 5F5.1 is validated for use in Western Blotting and Immunohistochemistry for the detection of PLA2R.

Western Blotting Analysis: 0.5 µg/mL from a representative lot detected PLA2R in 10 µg of human kidney tissue lysate.
Immunohistochemistry Analysis: A 1:250 dilution from a representative lot detected PLA2R in human kidney tissue.

Quality

Evaluated by Western Blotting in human lung tissue lysate.

Western Blotting Analysis: 0.5 µg/mL of this antibody detected PLA2R in 10 µg of human lung tissue lysate.

Target description

~180 kDa observed. Target band(s) appears larger than the calculated molecular weights (166.6 kDa/isoform 1 and 150.8 kDa/isoform 2) due to posttranslational glycosylation. Uncharacterized band(s) may appear in some lysates.

Physical form

Format: Purified
