Gene Information

human ... WIPI2(26100)

General description

WD repeat domain, phosphoinositide-interacting 2 belongs to the WIPI protein family. It is localized on the autophagy membrane and plasma membrane. Apart from this, it is also present on the membranes near the golgi cisternae. WIPI2 is a mammalian orthologous of Atg18, which is ubiquitously expressed in variety of cell lines.

Immunogen

WD repeat domain phosphoinositide-interacting protein 2 recombinant protein epitope signature tag (PrEST)

Application

Anti-WIPI2 antibody produced in rabbit has been used in immunofluorescence studies. All Prestige Antibodies®Powered by Atlas Antibodies is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

WIPI2 (WD repeat domain, phosphoinositide-interacting 2) plays a vital role in the transformation of omegasomes to autophagosomes. The above protein functions as a mammalian effector of phosphatidylinositol 3-phosphate (PtdIns3P). WIPI2 aids recombinant capsid protein VP1 (rVP1) in upregulating autophagy, MAPK1 (Mitogen-Activated Protein Kinase 1)/3 phosphorylation and matrix metallopeptidase 9 (MMP-9) activity, which are required for macrophage migration.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
