Protocol Available protocols: Western Blotting Specificity / Sensitivity NHERF1 (A140) Antibody detects endogenous levels of total NHERF1 protein. Species Reactivity: Human Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide surrounding Ala140 of human NHERF1. Antibodies are purified by peptide affinity chromatography. Background Na /H exchanger regulatory factor (NHERF1 or EBP-50) is one of several related PDZ domain-containing proteins (1). NHERF1 was first identified as a necessary cofactor for cyclic AMP-associated inhibition of Na / H exchanger isoform 3 (NHE3) (2). NHERF1 is a multifunctional adaptor protein that interacts with receptors and ion transporters via its PDZ domains, and with the ERM family of proteins, including merlin, via its carboxy-terminus (2,3). NHERF1 may play an important role in breast cancer. Estrogen has been found to induce NHERF1 in estrogen receptor-positive breast cancer cells (2,3). Furthermore, NHERF1 has been shown to bind to PDGFR, which is activated in breast carcinomas. NHERF1 has been found to promote the formation of a ternary complex containing PTEN, NHERF1, and PDGFR. Therefore, NHERF1 may function to recruit PTEN to PDGFR to inhibit the activation of PI3K/Akt signaling in normal cells; this mechanism may be disrupted in cancer (4). NHERF1 also binds to the cystic fibrosis transmembrane conductance regulator (CFTR), which functions as an ion channel and has disease-causing mutations in cystic fibrosis (5). Other proposed functions of NHERF1 include testicular differentiation, endosomal recycling, membrane targeting, protein sorting, and trafficking (6).
