The phrase "a typical pathway" is correct and usable in written English.
It can be used to describe a common or standard route or method to achieve a particular outcome or goal.
Example: "In the study of biology, a typical pathway for cellular respiration involves glycolysis, the Krebs cycle, and oxidative phosphorylation."
Alternatives: "a common route" or "a standard process."
Crucially, the research has revealed that those who become terrorists "are a diverse collection of individuals, fitting no single demographic profile, nor do they all follow a typical pathway to violent extremism".
(We could have analyzed a much larger network, but the results would not have been amenable to compact representation easily accessible to a reader; nonetheless, our current pathway model, presented in Figures 2 and 3, is much larger than a typical pathway described in a comprehensive review article).
The PERK/ATF4 signaling is now accepted as a typical pathway mediating ER stress-induced autophagy.
A related question is about the rules of thumb in pathway analysis: for example, if a typical pathway (network module?) has a size of N genes, what is the number of genes in this pathway m < N that would still register as an enrichment in some of the tests that the authors discuss?
While the mathematical model of Emonet et al. focuses on aspartate chemotaxis pathway, a typical adaptive pathway.
For example, according to the KEGG database (the most extensive pathway database at present), a typical glycolysis/gluconeogenesis pathway requires 49 enzymes, including 15 EC14 14 EC2, 6 EC3, 4 EC4, 8 EC5, and 2 enzymesymenzymes
The presence of a visual center independent of the typical pathway is interesting by itself, but also suggests that more non-conventional processing pathways may exist in centers for vision and other senses.
The electron transport chain is called the Z-scheme, a typical electron pathway comprising step-wise excitation using relatively low energy.
It has been demonstrated by several experiments that Rho-ROCK is a typical upstream pathway for the phosphorylation of moesin [ 23].
In a typical RNAi pathway, dsRNA is chopped into a siRNA duplex, where enriched pairing between antisense and sense small RNAs can be found [ 34, 35].
Beta oxidation at the heptanoic acid side chain is a typical transformation pathway for all statins, but is reported to play only a minor role in humans [ 75].
