NHERF2 / TRP channels
Name: Na(+)/H(+) exchange regulatory cofactor NHE-RF2
(NHERF2)
Official Symbol: SLC9A3R2
provided by HGNC
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 cAMP-mediated phosphorylation and inhibition of SLC9A3. May also act as scaffold protein in the nucleus.
