PDZD3 [ENSP00000327107]
 
PDZ domain containing 3; 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
GUCY2C [ENSP00000261170]
 
guanylate cyclase 2C (heat stable enterotoxin receptor); Receptor for the E.coli heat-stable enterotoxin (E.coli enterotoxin markedly stimulates the accumulation of cGMP in mammalian cells expressing GC-C). Also activated by the endogenous peptide guanylin
