PEDF R/PNPLA2 in Mouse Kidney. PEDF R/PNPLA2 was detected in perfusion fixed frozen sections of mouse kidney using 15 µg/mL Sheep Anti-Human/Mouse/Rat PEDF R/PNPLA2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5365) overnight at 4 °C. Tissue was stained with the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific labeling was localized to the plasma membrane of epithelial cells in tubules. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.
Detection of Human and Mouse PEDF R/PNPLA2 by Western Blot. Western blot shows lysates of human adipose tissue and mouse adipose tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human/Mouse/Rat PEDF R/PNPLA2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5365) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for PEDF R/PNPLA2 at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Detection of Mouse PEDF R/PNPLA2 by Simple WesternTM. Simple Western lane view shows lysates of mouse adipose tissue, loaded at 0.2 mg/mL. A specific band was detected for PEDF R/PNPLA2 at approximately 59 kDa (as indicated) using 10 µg/mL of Sheep Anti-Human/Mouse/Rat PEDF R/PNPLA2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5365) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: PEDF R/PNPLA2
PEDF R (Pigment epithelium derived factor receptor; also known as ATGL, PNPLA2, and Desnutrin) is a 55 kDa member of the PNPLA family of proteins. It is expressed in adipocytes, hepatocytes, skeletal muscle, and pigment epithelium. PEDF R specifically hydrolyses triglycerides, releasing long-chain fatty acids. Mouse PEDF R is described as being a 486 amino acid (aa) type II transmembrane (TM) protein. Its TM segment is stated to span aa 9-29. Alternatively, it may have a hydrophobic lipid-association domain between aa 267-295. It contains a palatin domain (aa 10-179) with a conserved GxSxG enzymatic motif. There are multiple splice forms. Two show alternate start sites at Met57 and Met232, while two others show a deletion of aa 163-196 and aa 253-308, respectively. Over aa 162-253, mouse PEDF R shares 98% and 93% aa sequence identity with rat and human PEDF R, respectively.
