 Context examples 

As part of a feedback loop, PKA can inhibit the activation of particulate guanylyl cyclase.

(Olfactory Transduction Pathway, NCI Thesaurus/KEGG)

Formin-dependent activation of BMP-antagonist Gremlin induces FGF4 and the SHH/FGF4 feedback loop.

(Oncogene HST, NCI Thesaurus)

By inhibiting mTOR to a lesser extent than PI3K, PQR309 does not interfere with the mTOR-mediated negative feedback loop on PI3K signaling.

(pan-PI3K/mTOR Inhibitor PQR309, NCI Thesaurus)

This allele, which encodes ubiquitin-protein ligase E3 Mdm2 protein, plays a role in the regulation of transactivation by tumor protein p53, as part of an autoregulatory negative feedback loop.

(MDM2 wt Allele, NCI Thesaurus)

Mdm-2 targets the p53 tumor suppressor for ubiquitin-dependent degradation by the proteasome, but, in addition, the p53 transcription factor induces Mdm-2, thus, establishing a feedback loop.

(Hypoxia Pathway, NCI Thesaurus/BIOCARTA)

This protein is directly phosphorylated by Tec in vitro where it participates in a positive feedback loop, increasing Tec activity.

(BCR Downstream Signaling 1, NCI Thesaurus)

This also removes the inhibition of PKA by DARPP-32, forming a positive feedback loop for further DARPP-32 inactivation by PKA.

(CK1/CDK5 Regulation Pathway, NCI Thesaurus/BIOCARTA)

In the nucleus, Per and Cry form a feedback loop that inhibits transcriptional activation by Bmal1 and Clock, lowering their own expression in the process.

(Circadian Rhythm Pathway BioCarta, NCI Thesaurus/BIOCARTA)

This protein is involved in blue light-dependent regulation of the circadian feedback loop.

(Cryptochrome-2, NCI Thesaurus)

In addition, as global temperatures continue to rise, demand for air conditioning – which emits greenhouse gases – rises as well, creating a damaging feedback loop.
