The phrase "activated by specific" is not complete and lacks clarity in written English.
It can be used when discussing processes or mechanisms that are triggered by particular conditions or factors, but it needs additional context to be fully understandable.
Example: "The enzyme is activated by specific molecules that bind to its active site."
Alternatives: "triggered by particular" or "initiated by specific".
These cell death genes must not be constitutively active, but are selectively activated by specific signals to promote cell autonomous death.
This may be due to the fact that while neopterin is considered to be a general marker of immune activation, IDO is only activated by specific immune agents [ 13].
The noncanonical NF-κB activation pathway, which can be activated by specific members of the TNF receptor family (e.g., lymphotoxin β receptor [LTβR] and BAFF receptor [BAFF-R]) depends on IKKα (IKK1) and NIK kinase activity but not on IKKβ or IKKγ [1].
Since the relative effect on transcriptional vs translational regulation is likely to depend on the intracellular signaling pathways activated by specific stimuli, we compared ET-1 (potent activation of ERK1/2 with minimal activation of PI3K and PKB/Akt) and insulin (potent activation of PI3K and PKB/Akt with minimal activation of ERK1/2) [ 19].
Present at low levels in all cells, PKR is activated by double-stranded RNA, other polyanionic molecules such as heparin, and the protein activator PACT, and has been shown to be important in transcriptional pathways activated by specific cytokines [ 21, 26], growth factors [ 27], and extracellular stresses [ 28].
Produced by lymphocytes activated by specific antigens or mitogens, IFN-gamma, in addition to having antiviral activity, has important immunoregulatory functions.
Generally, inactive zymogens of caspases, known as procaspases, are synthesized constitutively and activated by specific proteolytic cleavage4,5.
Intact, these proteins display the sophisticated allosteric behavior required for cellular regulation; the protein's output activity is tightly repressed under basal conditions, but can be robustly activated by a specific set of input effector ligands.
These engineered receptors no longer respond to endogenous peptides, but can still be activated by a specific small-molecule drug.
You can choose to make it effective from the moment you sign it, or specify that it be activated by a specific event, for instance, if you become incompetent.
These results suggest that T7 RNA polymerase was activated by the specific binding of the polyamine additive to produce RNA transcripts with fidelity to the template DNA.
