General Notes
This product (Catalog No. DPABH-05718) is a rabbit-derived polyclonal antibody raised against human WIPI1, targeting the amino acid region 346–446 of the protein. This antibody exhibits cross-reactivity with Human WIPI1 from mouse. It has been affinity purified by Protein A. WIPI1, or WD repeat domain, phosphoinositide-interacting protein 1, is a member of the WD40 repeat family of proteins, which are key components of many essential biological functions. WIPI1 is involved in the regulation of autophagy, a cellular process critical for maintaining cellular integrity and recycling intracellular proteins, lipids, and organelles. WIPI1 is characterized by its 7-bladed β-propeller structure and contains a conserved motif for interaction with phospholipids, specifically binding to phosphoinositides. This interaction is crucial for its function in autophagy, where it acts as an effector of phosphatidylinositol 3-phosphate (PtdIns3P). WIPI1 and WIPI2 are among the first proteins to be recruited during autophagy, with WIPI2 interacting with components of the ULK1/2 complex and PtdIns3P, tethering the phagophore to the endoplasmic reticulum (ER). WIPI1 supports the function of WIPI2 in recruiting the ATG16L complex, which is essential for LC3 lipidation and autophagosome formation.
DPABH-05718 is suitable for use in Western blot (WB) (1:500–1:2,000), IHC (1:50–1:500) applications.
DPABH-05718 is supplied as a liquid formulation in PBS with 0.02% sodium azide and 50% glycerol, pH 7.3. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
