Ezrin

Gene

EZR

Organism
Bos taurus (Bovine)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Probably involved in connections of major cytoskeletal structures to the plasma membrane. In epithelial cells, required for the formation of microvilli and membrane ruffles on the apical pole. Along with PLEKHG6, required for normal macropinocytosis (By similarity).By similarity

Enzyme regulationi

A head-to-tail association, of the N-terminal and C-terminal halves results in a closed conformation (inactive form) which is incapable of actin or membrane-binding.By similarity

Post-translational modificationi

Phosphorylated by tyrosine-protein kinases. Phosphorylation by ROCK2 suppresses the head-to-tail association of the N-terminal and C-terminal halves resulting in an opened conformation which is capable of actin and membrane-binding (By similarity).By similarity
S-nitrosylation is induced by interferon-gamma and oxidatively-modified low-densitity lipoprotein (LDL(ox)) possibly implicating the iNOS-S100A8/9 transnitrosylase complex.By similarity

Interactioni

Subunit structurei

Interacts with MPP5 and SLC9A3R2. Found in a complex with EZR, PODXL and SLC9A3R2 (By similarity). Interacts with MCC, PLEKHG6, PODXL, SCYL3/PACE1, SLC9A3R1 and TMEM8B. Interacts (when phosphorylated) with FES/FPS. Interacts with dimeric S100P, the interaction may be activating through unmasking of F-actin binding sites (By similarity). Identified in complexes that contain VIM, EZR, AHNAK, BFSP1, BFSP2, ANK2, PLEC, PRX and spectrin (By similarity). Detected in a complex composed of at least EZR, AHNAK, PPL and PRX (PubMed:14625392).By similarity1 Publication
