Previously characterized mammalian soluble guanylyl cyclases form alpha/beta heterodimers that can be activated by the gaseous messenger, nitric oxide, and the novel guanylyl cyclase modulator YC-1. Four mammalian subunits have been cloned named alpha(1), beta(1), alpha(2), and beta(2). The alpha(1)/beta(1) and alpha(2)/beta(1) heterodimeric enzyme isoforms have been rigorously characterized. T...
The intestinal guanylyl cyclase-C (GC-C) was originally identified as an Escherichia coli heat-stable enterotoxin (STa) receptor. STa stimulates GC-C to much higher activity than the endogenous ligands guanylin and uroguanylin, causing severe diarrhea. To investigate the interactions of the endogenous and bacterial ligands with GC-C, we designed and characterized a soluble and properly folded f...
The role of cGMP in olfactory signaling is not fully understood, but it is believed to play a modulatory role in intracellular signaling in vertebrate olfactory receptor neurons (ORNs). Here, we present evidence that cGMP in ORNs may play an important role in recognition of biologically relevant odors and olfactory learning. Specifically, we investigated the cellular mechanisms underlying olfac...
