NHERF4 / TRP channels

Name: Na(+)/H(+) exchange regulatory cofactor NHE-RF4 (NHERF4)
Official Symbol: PDZD3 provided by HGNC
Function:
Acts as a regulatory protein that associates with GUCY2C and negatively modulates its heat-stable enterotoxin-mediated activation. Stimulates SLC9A3 activity in the presence of elevated calcium ions.
