Descrizione generale

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.

Immunogeno

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

Applicazioni

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

Azioni biochim/fisiol

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.

Stato fisico

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
