 Context examples 

The main signaling mechanism used by GPCRs is to interact with G-protein GTPase proteins coupled to downstream second messenger systems including intracellular calcium release and cAMP production.

(Bioactive Peptide Signaling Pathway, NCI Thesaurus/BIOCARTA)

This allele, which encodes breast carcinoma amplified sequence 2 protein, plays a role in the mediation of messenger RNA splicing.

(BCAS2 wt Allele, NCI Thesaurus)

This gene plays a role in G protein-coupled receptor signal transduction that results in the stimulation of the phosphatidylinositol-calcium second messenger pathway.

(AVPR1B Gene, NCI Thesaurus)

These factors stimulate phospholipase C through Gq activation, and the production of 1P3 and diacylglycerol second messengers.

(Cardiac Hypertrophy Pathway, NCI Thesaurus/BIOCARTA)

This allele, which encodes protein CASC3, plays a role in the regulation of nonsense-mediated messenger RNA decay.

(CASC3 wt Allele, NCI Thesaurus)

Csk activity is regulated in T cells by PKA, the cAMP-dependent protein kinase activated by the second messenger cAMP.

Ceramide is the core molecule for the synthesis of sphingomyelin, an essential lipid for myelination and neurotransmission; it may function as a second messenger to stimulate differentiation, inhibit proliferation, and induce apoptosis.

(Ceramide, NCI Thesaurus)

The G-protein coupled receptor (GPCR) family transduces extracellular signals across the plasma membrane, activating cellular responses through a variety of second messenger cascades (see PKA and PKC signaling pathways).

(Attenuation of GPCR Signaling Pathway, NCI Thesaurus/BIOCARTA)
