Article body
A guanylate cyclase activator (or "GUCA") is a member of a group of proteins that upregulate guanylate cyclase. GUCA is also known as guanylate cyclase-activating protein (or "GCAP"). Its mutations can be associated with vision defects.

There are several therapeutic drugs that act as GUCAs, including linaclotide and plecanatide, which are guanylate cyclase-C receptor agonists. These drugs increase the secretion of bicarbonate and chloride in the colon and potentially relieve visceral hypersensitivity in IBS-C patients.
