Beschreibung

General description

Ezrin (UniProt Q8HZQ5; also known as Cytovillin, Villin-2, p81) is encoded by the EZR (also known as VIL2) gene (Gene ID 100008846) in Oryctolagus cuniculus (Rabbit) species. Ezrin, radixin, and moesin are the three ERM protein family members that crosslink actin filaments with plasma membranes and play an important role in the cell cortex architecture. In its inactive state, ezrin is located in the cytosol in a conformation involving intramolecular interaction between its N- and C-terminal. Ezrin is activated by phosphorylation, which causes a conformation change that disrupts the head-to-tail intramolecular interaction. Upon activation, ezrin binds to the cytoplasmic tails of multiple adhesion and signaling membrane molecules, such as CD44, growth factor receptors, and vascular adhesion molecule (VCAM1). The initiator methionine of ezrin is removed posttranslationally to yield the mature protein (a.a. 2-586) with an N-termina FERM domain (a.a. 2-295) that mediates interaction with microtubules.

~75 kDa observed. 69.41 kDa (Human/UniProt P15311 & Mouse/P26040), 69.39 kDa (Rat/UniProt P31977), and 69.22 kDa (Rabbit/Q8HZQ5) calculated. Uncharacterized band(s) may appear in some lysates.

Western Blotting Analysis: 0.5 µg/mL of this antibody from a representative lot detected Ezrin in 10 µg of HeLa cell lysate.
Immunohistochemistry Analysis: A representative lot detected a higher Ezin immunoreactivity in paraffin-embedded human medulloblastoma sections when compared with normal cerebellum sections (Haeberle, H., et al. (2012). Neoplasia. 14(7):666-669).
Immunohistochemistry Analysis: A representative lot immunostained parietal cells in rabbit gastric mucosa (Hanzel, D.K., et al. (1989). Am. J. Physiol. 256(6 Pt 1):G1082-G1089).
Immunoprecipitation Analysis: A representative lot immunoprecipitated Ezin from human A431 cells. The immunoprecipitated Ezrin was phosphorylated on Ser66 from dbcAMP‐treated, but not cAMP‐treated, A431 cells (Wang, S., et al. (2009). Cell Res. 19(12):1350-1362).
Electron Microscopy Analysis: A representative lot detected Ezrin on microvilli of the intracellular canaliculi (IC) and the subapical region of resting parietal cells in Lowicryl HM20-embedded rabbit gastric gland ultrathin sections (Sawaguchi, A., et al. (2004). J. Histochem. Cytochem. 52(1): 77–86).
Immunocytochemistry Analysis: A representative lot detected exogenously expressed human GST fusion protein by fluorescent immunocytochemistry staining of formaldehyde-fixed, Triton X-100-permeabilized rabbit gastric parietal cells (Zhou, R., et al. (2003). J. Biol. Chem. 278(37):35651-35659).
Western Blotting Analysis: A representative lot detected both the endogenous rabbit Ezrin as well as exogenously expressed human Ezrin GST fusion proteins in transfected rabbit gastric parietal cells (Zhou, R., et al. (2003). J. Biol. Chem. 278(37):35651-35659).
ELISA Analysis: Clone 4A5 hybridoma culture supernatant was screened for its immunoreactivity by ELISA and found to react with both dentured and non-denatured 80 kDa Ezrin preparations from rabbit gastric glands/mucosa vesicular fractions (Hanzel, D.K., et al. (1989). Am. J. Physiol. 256(6 Pt 1):G1082-G1089).
