Protein

Na(+)/H(+) exchange regulatory cofactor NHE-RF2

Gene

Slc9a3r2

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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.1 Publication

Expressioni

Tissue specificityi

Glomerular epithelium cell (podocyte) (at protein level). Detected in liver, bile duct, kidney glomerulus and lung.2 Publications

Interactioni

Subunit structurei

Homodimer, and heterodimer with SLC9A3R1. Binds ADRB2, SLC9A3, P2RY1, P2YR2, SRY, RDX, PDZK1 and LPAR2 (By similarity). 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. Interacts with SGK1 and KCNJ1/ROMK1 (By similarity). Interacts (via the PDZ domains) with SLC26A6 (By similarity).By similarity
