SLC9A3R2 Antibody – Rabbit

This gene encodes a member of the NHERF family of PDZ scaffolding proteins. These proteins mediate many cellular processes by binding to and regulating the membrane expression and protein-protein interactions of membrane receptors and transport proteins. The encoded protein plays a role in intestinal sodium absorption by regulating the activity of the sodium/hydrogen exchanger 3, and may also regulate the cystic fibrosis transmembrane regulator (CFTR) ion channel. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011]

NHERF-2: 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 cAMP-mediated phosphorylation and inhibition of SLC9A3. May also act as scaffold protein in the nucleus. Homodimer, and heterodimer with SLC9A3R1. Binds PDZK1. Found in a complex with EZR, PODXL and SLC9A3R2. Interacts (via the PDZ domains) with PODXL (via the C-terminal PDZ-binding motif DTHL); interaction is detected in glomerular epithelium cells. Binds ADRB2, SLC9A3, P2RY1, P2YR2, SRY, RDX and LPAR2. Interacts with MCC and PODXL. Interacts with SGK1 and KCNJ1/ROMK1. Widely expressed. 2 isoforms of the human protein are produced by alternative splicing.
