Disease

[NHERF_HUMAN] Defects in SLC9A3R1 are the cause of hypophosphatemic nephrolithiasis/osteoporosis type 2 (NPHLOP2) [MIM:612287]. Hypophosphatemia results from idiopathic renal phosphate loss. It contributes to the pathogenesis of hypophosphatemic urolithiasis (formation of urinary calculi) as well to that of hypophosphatemic osteoporosis (bone demineralization).^[1] ^[2]

Function

[RADI_MOUSE] Probably plays a crucial role in the binding of the barbed end of actin filaments to the plasma membrane. [NHERF_HUMAN] 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 (By similarity). Involved in the regulation of phosphate reabsorption in the renal proximal tubules.^[3] ^[4] ^[5] ^[6]

Publication Abstract from PubMed

The Na+/H+ exchanger regulatory factor (NHERF) is a key adaptor protein involved in the anchoring of ion channels and receptors to the actin cytoskeleton through binding to ERM (ezrin/radixin/moesin) proteins. NHERF binds the FERM domain of ERM proteins, although NHERF has no signature Motif-1 sequence for FERM binding found in adhesion molecules. The crystal structures of the radixin FERM domain complexed with the NHERF-1 and NHERF-2 C-terminal peptides revealed a peptide binding site of the FERM domain specific for the 13 residue motif MDWxxxxx(L/I)Fxx(L/F) (Motif-2), which is distinct from Motif-1. This Motif-2 forms an amphipathic alpha helix for hydrophobic docking to subdomain C of the FERM domain. This docking causes induced-fit conformational changes in subdomain C and affects binding to adhesion molecule peptides, while the two binding sites are not overlapped. Our studies provide structural paradigms for versatile ERM linkages between membrane proteins and the cytoskeleton.
