Description_x000D_ General description_x000D_ 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._x000D_ Application_x000D_ Monoclonal Anti-WIPI-1 antibody has been used in immunoblotting, immunoprecipitation._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ 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.
