Anti-NHERF1 / SLC9A3R1, clone IIH-19

Antibody in PBS with 0.02% sodium azide, 50% glycerol and 0.4-0.5mg/ml BSA. The SLC9A3R1 gene encodes a sodium/hydrogen exchanger regulatory cofactor. Na(+)/H(+) exchange regulatory cofactor NHE-RF1 (also called SLC9A3 regulator 1 and Ezrin-radixin-moesin-binding phosphoprotein 50) interacts with and regulates various proteins including the cystic fibrosis transmembrane conductance regulator and G-protein coupled receptors such as the beta2-adrenergic receptor and the parathyroid hormone 1 receptor. The protein also interacts with proteins that function as linkers between integral membrane and cytoskeletal proteins. The protein localizes to actin-rich structures including membrane ruffles, microvilli, and filopodia. Mutations in this gene result in hypophosphatemic nephrolithiasis/osteoporosis type 2, and loss of heterozygosity of this gene is implicated in breast cancer. [RefSeq] Protein function: Scaffold protein that connects plasma membrane proteins with members of the ezrin/moesin/radixin family and thereby helps to link them to the actin cytoskeleton and to regulate their surface expression. Necessary for recycling of internalized ADRB2. Was first known to play a role in the regulation of the activity and subcellular location of SLC9A3. Necessary for cAMP-mediated phosphorylation and inhibition of SLC9A3. May enhance Wnt signaling. May participate in HTR4 targeting to microvilli. Involved in the regulation of phosphate reabsorption in the renal proximal tubules. Involved in sperm capacitation. May participate in the regulation of the chloride and bicarbonate homeostasis in spermatozoa. [The UniProt Consortium]
