The phrase "activation is controlled" is correct and usable in written English.
You can use it in contexts where you are discussing the regulation or management of a process or system that involves activation.
Example: "In this experiment, we found that activation is controlled by specific environmental factors that influence the reaction rate."
Alternatives: "activation is regulated" or "activation is managed".
Gli2 is the major Hh pathway transcriptional activator; its activation is controlled by translocation to the cilium (Humke et al., 2010; Tukachinsky et al., 2010).
The crux of this issue concerns both when KNa current is active and how any activation is controlled by Na+.
GLUT4 activation is controlled by regulatory proteins which activate either the AMPK or PI3K pathway.
NK cell activation is controlled by a number of activating and inhibitory receptors [2].
NK cell activation is controlled by complex interactions between activating or inhibitory receptors and their associated ligands.
NK cell activation is controlled by a balance of signals from activating and inhibitory receptors, which recognize cognate ligands expressed by potential target cells (Vivier et al., 2011; Shifrin et al., 2014).
Therefore, a question is raised concerning how the signal amplitude of the signal transduction pathway and the cell-specific activation were controlled in the ErbB receptor co-expression system.
Meanwhile, APC activation was controlled by a time-delay mechanism through the 'intermediary enzyme' IE in Fig. 3a.
Successful receptor activation was controlled by Western blot (Additional file 1, Figure S1a) and realtime PCR (Additional file 1, Figure S1b).
We, therefore, hypothesized that p18 formation and MAPK activation are controlled by the ratio of p43/p41 and p43-FLIP at the DISC.
Leishmania elimination by phagocytes is a crucial step for infection control and several reports have demonstrated that their effective and persistent activation are controlled by cytokines derived from the adaptive immunity [ 29, 30].
