Immunofluorescent analysis of EBP50 was performed using 70% confluent log phase T-47D cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with EBP50 Rabbit Polyclonal Antibody (PA1-090) at 2ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (A27034) a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

PA1-090 detects ezrin-radixin-moesin (ERM) binding phosphoprotein of 50 kDa (EBP50) from mouse tissues, human T84 and Calu3 cells as well as recombinant human protein.
PA1-090 has been successfully used in Western blot, Immunohistochemistry, immunoflourescence and immunoprecipitation procedures. By Western blot, this antibody detects an ~50 kDa protein representing EBP50 from T84 cell extract. Immunohistochemical staining of EBP50 in mouse airway results in staining of the epithelium.
The PA1-090 immunogen is recombinant human His-tagged EBP50 obtained from bacteria. All His-tag specific antibody has been removed. This product was epitope affinity purified using a synthetic peptide to residues C R(286) S A S S D T S E E L N S Q D S P(302) of human EBP50
EBP50 [ERM (ezrin-radixin-moesin) binding phosphoprotein of 50 kDa] is a PDZ containing protein that is involved in the linkage of integral membrane proteins to the cytoskeleton. EBP50 contains two tandem PDZ domains followed by a carboxy-terminal sequence that binds to members of the ERM family of membrane-cytoskeleton adaptors. The PDZ domains within EBP50 bind to the carboxy termini of such target proteins as beta2 adrenergic receptor, platelet-derived growth factor receptor (PDGFR), and the cystic fibrosis conductance regulator (CFTR). The PDZ domains are also believed to be involved in the oligomerization of EBP50 to form multiprotein complexes which helps to facilitate the formation of functional signalling complexes.
EBP50 has been shown to link integral membrane proteins to the cytoskeleton by binding to members of the ERM family of proteins, which bind to F-actin. Through these interactions, EBP50 is implicated in the localization of interactive groups of proteins into subcellular domains and in the regulation of activity of those interacting proteins. Immunohistochemical studies have shown that EBP50 is found exclusively at the apical membranes of epithelial cells.
