General description
Monoclonal Anti-WIPI-1 (mouse IgG1 isotype) is derived from the hybridoma WIPI1-4 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic peptide corresponding to a fragment of human WIPI-1, conjugated to KLH. WIPI-1 (WD repeat domain phosphoinositide-interacting protein 1) the mammalian orthologue of Atg18 in S. cerevisiae and A. thaliana, is a member of the WIPI subfamily of WD-repeat (Trp-Asp) proteins. WIPI-1 has a 7-bladed propeller structure and contains a conserved motif for interaction with phospholipids. WIPI-1 is expressed in normal human tissues with high levels in skeletal muscle, heart and testis.
Application
Monoclonal Anti-WIPI-1 antibody has been used in immunoblotting, immunoprecipitation.
Biochem/physiol Actions
WIPI-1 (WD repeat domain phosphoinositide-interacting protein 1) plays an important role in signal transduction, transcription regulation and apoptosis. Endogenous WIPI-1 partially colocalizes with the autophagosomal marker LC3 and induction of autophagy leads to the accumulation of WIPI-1 in large vesicular and cup-shaped structures that are characteristic for autophagy-linked proteins. WIPI-1 is aberrantly expressed in human cancer and is linked to starvation induced autophagy.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Macroautophagy is an intracellular degradation system for the majority of proteins and some organelles. The molecular mechanism of autophagy has been extensively studied using the yeast, Saccharomyces cerevisiae, during these past 10 years. These studies suggested that the molecular machinery

Autophagy depends on the activity of phosphoinositide-3 kinase class III to generate PI(3)P. We identified the human WIPI protein family of PI(3)P-binding factors and showed that WIPI-1 (Atg18) is linked to autophagy in human cells. Induction of autophagy by rapamycin

WD-repeat proteins are regulatory beta-propeller platforms that enable the assembly of multiprotein complexes. Here, we report the functional and bioinformatic analysis of human WD-repeat protein Interacting with PhosphoInosides (WIPI)-1alpha (WIPI49/Atg18), a member of a novel WD-repeat protein family with autophagic
