Sentences with phrase «cyclase by»

The characteristics of this phenomenon paralleled those of the activation of guanylate cyclase by nitric oxide, which is a component of tobacco smoke.

Although type I adenylyl cyclase is inhibited directly by exogenous beta gamma, inhibition of adenylyl cyclase by Gi alpha has not been convincingly demonstrated in vitro.

Concentration - dependent inhibition of adenylyl cyclases by purified Gi alpha subunits is described.

His doctoral research focused on the regulation of the ERK / MAPK pathway by adenylyl cyclases during long - term memory formation and sensitization to drugs of abuse.

The alpha 2 and beta 2 adrenergic receptors, both of which are activated by epinephrine, but which can be differentiated by selective drugs, have opposite effects (inhibitory and stimulatory) on the adenylyl cyclase system.

In the presence of Gs alpha, the alpha subunit of the G protein that activates adenylyl cyclase, one form of adenylyl cyclase was inhibited by beta gamma, some forms were activated by beta gamma, and some forms were not affected by beta gamma.

The plasma membrane of hepatic parenchymal cells contains an adenyl cyclase system that is stimulated by glucagon.

These findings support the concept that glucagon exerts its regulatory action in the liver by stimulating adenyl cyclase activity in the plasma membrane.

An adenylate cyclase that is activated specifically by very low concentrations of octopamine has been identified both in homogenates and in intact cells of the thoracic ganglia of an insect nervous system.

Receptor molecules coded by the 7 - repeat allele have been found to have a lower potency for dopamine - mediated coupling to adenylate cyclase than receptors encoded by the other frequent, 2 - or 4 - repeat forms [90], and more recent results suggest an additional effect of the 48 bp VNTR on gene expression [91, 92].
