The Department of Homeland Security – an agency far better prepared to defend against threats – might be a better home for such a defensive function.
The venom, however, also serves a defensive function, and is, therefore, highly lethal to vertebrates, including mammals.
- In 1948, Hinton reviewed the mechanisms of sound/vibration production in the pupae of Lepidoptera, and suggested a defensive function against predators.
However, this protein also has a defensive function, having been demonstrated that fibrinogen concentration increases during acute-phase reactions [ 55, 56].
In addition to finding that cigarette smoke (CS) impacts the functioning of key pathways with significant roles in redox homeostasis, xenobiotic detoxification, cell cycle control, and endoplasmic reticulum (ER) functioning, our data highlighted a defensive role for the unfolded protein response (UPR) program.
The gut is colonized by trillions of bacteria that perform vital metabolic and defensive functions for the host.
In addition to their roles in regulating endogenous metabolites, SULTs provide a critical defensive function; they detoxify compounds, particularly xenobiotics, by preventing them from binding adventitiously to receptors and target them for degradation and elimination.
The marginal markings on Sophogramma lii likely had a similar defensive function, misleading predators to attack the wing margin instead of vital, axially located body parts.
An analysis of the sequence variation revealed that the active domains of PI genes carry the signatures of an evolutionary arms race between plants and their enemies [9], [62]; hence the ability to produce a wide spectrum of structurally and functionally divergent PIs is likely important for PIs' defensive function.
