Inosine 3′:5′-cyclic monophosphate (cIMP) is used in studies that compare the substrate specificity and activity of cyclic purines, including the 3′,5′-cyclic monophosphates cAMP and cGMP.

The enhancement of the transcription of three synthetic promoters by cNMP-ligated cAMP receptor protein (CRP)/mutant complexes was determined from the transcription yields of a short AAUU transcript in an abortive initiation in vitro transcription assay. The cNMP-ligated CRP and mutants

The effects of extracellular purinergic agonists and their breakdown products on glucose and glutamine synthesis in rabbit kidney-cortex tubules incubated with aspartate + glycerol or alanine + glycerol + octanoate were investigated. A rapid extracellular degradation of ATP was accompanied

External application of the 3',5'-cyclic monophosphates of inosine, cytidine, uridine and thymidine stimulated the fluid secretion rate (FSR) of Malpighian tubules isolated from Drosophila melanogaster. The evidence suggested that the cyclic nucleotides acted intracellularly in some capacity. Receptors of the
In vertebrate olfactory receptors, cAMP produced by odorants opens cyclic nucleotide-gated (CNG) channels, which allow Ca(2+) entry and depolarization of the cell. These CNG channels are composed of alpha subunits and at least two types of beta subunits that are

Cyclic nucleotide-gated (CNG) channels belong to the P-loop-containing family of ion channels that also includes KcsA, MthK, and Shaker channels. In this study, we investigated the structure and rearrangement of the CNGA1 channel pore using cysteine mutations and cysteine-specific modification.
