Guanylate cyclase 2C, also known as guanylyl cyclase C (GC-C), intestinal guanylate cyclase, guanylate cyclase-C receptor, or the heat-stable enterotoxin receptor (hSTAR) is an enzyme that in humans is encoded by the GUCY2C gene.[5][6]

Guanylyl cyclase is an enzyme found in the luminal aspect of intestinal epithelium and dopamine neurons in the brain.[7] The receptor has an extracellular ligand-binding domain, a single transmembrane region, a region with sequence similar to that of protein kinases, and a C-terminal guanylate cyclase domain. Tyrosine kinase activity mediates the GC-C signaling pathway within the cell.

Functions

GC-C is a key receptor for heat-stable enterotoxins that are responsible for acute secretory diarrhea.[8] Heat-stable enterotoxins are produced by pathogens such as Escherichia coli. Knockout mice deficient in the GC-C gene do not show secretory diarrhea on infection with E. coli, though they do with cholera toxin. This demonstrates the specificity of the GC-C receptor.

gollark: I like the statelessness thing, but not the resource-oriented thing.

gollark: Also also, people cannot actually agree on what it is and what it means you should do half the time.

gollark: Also, people often want to do things like "restart" in their API, which it can't nicely express, and end up contorting it horribly.

gollark: REST seems kind of bad to me. It feels kind of layer-violationy using HTTP things to signal application-level statuses, and a lot of the time both ends would have less code just using a RPC-style interface, which has unfortunately fallen out of fashion.
