The phrase "activating segment" is correct and usable in written English.
It can be used in contexts related to technology, marketing, or any field where a specific part or component is responsible for initiating a process or action.
Example: "The activating segment of the software is crucial for ensuring that all features function correctly upon startup."
Alternatives: "triggering component" or "initiating part".
PDK1 is integral to the PI3K/AKT pathway, as it phosphorylates the activating segment of AKT, a potent proto-oncogene involved in a variety of cellular functions such as proliferation and survival.
The mutations are either in the activating segment in exon 15 or the glycine-rich loop (P-loop) in exon 11 of the kinase domain of the BRAF protein.
The point mutation in DNA (1799T → A) resulting in a single amino-acid substitution at Valine 600 to Glutamic acid in the activating segment (V600E, previously known as V599E) is the most common change, and is found in 80% of the mutated tumours (Davies et al, 2002).
The latest mechanically activated segment had the largest phase angles.
Stalk cells are represented by one activated segment adjacent to the tip cell and by any number of nonadjacent, quiescent segments.
As the adjacent stalk cells change position and shape, their segments can change in number and radius, and the activated segment closest to the tip cell can change in length and radius.
But Trump carried on — in part because he had activated segments of the electorate that other candidates could not, or would not.
We know the mutations associated with developmental syndromes cause a modest activation of MEK activity compared with activating mutations in the activation segment.
Dephosphorylation of Tyr527 converts Src to an open active conformation and triggers autophosphorylation of the activation segment residue Tyr416 to yield a fully activated enzyme.
To attain full activity, CDKs require cyclin-binding and phosphorylation within the activation segment (T-loop) by a CDK-activating kinase (CAK) [1].
Yet, in the absence of dimerization and activation segment exchange, CHK1 cannot phosphorylate activation segment residues and activate CHK2, as they do not resemble CHK1 consensus substrates.
