Regions on adenylyl cyclase VII required for selective regulation by the G13 pathway.
Regulation of multiple adenylyl cyclases (AC) provides unique inputs to mediate the synthesis of cAMP, a ubiquitous second messenger that controls many aspects of cellular function. On stimulation by G(s), the activities of ACs can be further selectively modulated by other pathways to ensure precise control of intracellular cAMP responses to specific stimuli. Recently, we reported that one of t...

Regulation of multiple adenylyl cyclases (AC) provides unique inputs to mediate the synthesis of cAMP, a ubiquitous second messenger that controls many aspects of cellular function. On stimulation by Gs, the activities of ACs can be further selectively modulated by other pathways to ensure precise control of intracellular cAMP responses to specific stimuli.

متن کاملRegulation of cAMP responses by the G12/13 pathway converges on adenylyl cyclase VII.
Regulation of intracellular cAMP by multiple pathways enables differential function of this ubiquitous second messenger in a context-dependent manner. Modulation of G(s)-stimulated intracellular cAMP has long been known to be modulated by the G(i) and G(q)/Ca(2+) pathways. Recently, the G(13) pathway was also shown to facilitate cAMP responses in murine macrophage cells. We report here that thi...
متن کاملRegulation of adenylyl cyclase by membrane potential.
Mammalian adenylyl cyclases possess 12 transmembrane-spanning domains and bear a superficial resemblance to certain classes of ion channels. Some evidence suggests that bacterial and sea urchin sperm adenylyl cyclases can be regulated by membrane depolarization. In the present study, we explored the effect of altering membrane potential on the adenylyl cyclase activity of cerebellar granule cel...
متن کاملLithium preferentially inhibits adenylyl cyclase V and VII isoforms.
Lithium ions' inhibition of adenylyl cyclase (AC) has not been previously studied for the newly discovered AC isoforms. COS7 cells were transfected with each of the nine membrane-bound AC isoforms cDNAs with or without D1- or D2-dopamine receptor cDNA. AC activity was measured as [3H]cAMP accumulation in cells pre-incubated with [3H]adenine followed by incubation with phosphodiesterase inhibito...
