Receptor guanylyl cyclase (RGC) family C


« Hide

The mammalian genome encodes transmembrane and soluble receptor guanylyl cyclases, both of which have enzyme activities which convert guanosine-5'-triphosphate to the intracellular second messenger cyclic guanosine-3',5'-monophosphate (cyclic GMP).

The polysaccharide obtained from fermentation of Aureobasidium species, HS-142-1, acts as an antagonist at both GC-A and GC-B receptors [4]. GC-D and GC-G have been reported to be activated intracellularly by guanylyl cyclase-activating protein 1 (GUCA1A, P43080) and guanylyl cyclase-activating protein 2 (GUCA1B, Q9UMX6). GC-D and GC-G may be activated by atmospheric levels of CO2 through the formation of intracellular bicarbonate ions [2-3]. GC-G may be activated at cooler temperatures (20-25°C) through apparent stabilisation of the dimer [1].
