The mTORC1 complex comprises RAPTOR, mLST8 and PRAS40 and when activated, initiates cell growth, proliferation and protein synthesis by regulating S6K1 and 4E-BP1 [ 47].
Most cells have intracellular sensors of viral products that, when activated, initiate a signaling cascade that results in transcriptional induction of the IFNβ gene.
The contact system, which consists of factor (F) XII, FXI, prekallikrein, and high molecular weight kininogen (HK), is a plasma protease cascade that, when activated, initiates the intrinsic pathway of coagulation (Additional file 1: Figure S1).
CD47 serves as the ligand of SIRP α, which is expressed on phagocytic cells and, when activated, initiates a signal transduction cascade resulting in the inhibition of phagocytosis 32– 32.
3 The 5-HT3 receptor is a ligand-gated ion channel present on the abdominal vagal afferents which, when activated, initiates a cascade of signals throughout the central nervous system to cause the sensation of nausea and the act of vomiting via multiple efferent pathways.
Aurora-A kinase localizes at the centrosome in interphase and is activated for initiating mitotic entry (Hirota et al., 2003; Macurek et al., 2008; Seki et al., 2008).
Once activated, PRRs initiate signaling cascades leading to the activation of the transcription factor NF-κB and mitogen-associated protein kinases (MAPKs).
When an agent is activated, she initiates a collaboration.
Further advances unravelled how some prototypical PRRs get activated to initiate metabolic adaptation and defence responses that stop invaders.
