Allgemeine Beschreibung

WIPI-1, the mammalian orthologue of Atg18 in S. cerevisiae and A. thaliana, is a member of the WIPI subfamily of WD-repeat proteins. It has a 7-bladed propeller structure and contains a conserved motif for interaction with phospholipids. WIPI-1 is ubiquitously expressed in normal human tissues with highest levels in skeletal muscle, heart and testis. It is aberrantly expressed in human cancer.

Immunogen

synthetic peptide corresponding to amino acids 406-421 of human WIPI-1, conjugated to KLH. The corresponding sequence is identical in mouse and rat.

Anwendung

Anti-WIPI-1 (C-terminal) antibody produced in rabbit has been used in immunoblotting and immunoprecipitation.

Biochem./physiol. Wirkung

WIPI-1 has essential biological functions including signal transduction, transcription regulation and apoptosis. WD-repeat proteins regulate the assembly of multiprotein complexes by presenting a β-propeller platform for simultaneous and reversible protein-protein interactions. WIPI-1 is linked to starvation-induced autophagy.

Physikalische Form

Solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide.

Autophagosome formation requires PROPPIN/WIPI proteins and monophosphorylated phosphoinositides, such as phosphatidylinositol-3-phosphate (PtdIns3P) or PtdIns5P. This process occurs in association with mammalian endosomes, where the PROPPIN WIPI1 has additional, undefined roles in vesicular traffic. To explore whether these functions are interconnected
Thibault Courtellemont et al.
The EMBO journal, 41(10), e109646-e109646 (2022-04-26)
Endo-lysosomal compartments exchange proteins by fusing, fissioning, and through endosomal transport carriers. Thereby, they sort many plasma membrane receptors and transporters and control cellular signaling and metabolism. How the membrane fission events are catalyzed is poorly understood. Here, we identify
