Complex formation allows proteolytic activation of procaspase into the active caspase form which results in the initiation of apoptosis (cell death).

Having heard nothing more from General Eiger, Katya believes the situation to be hopeless and wants to stop responding to the alarm, allowing activation of the weapon.

Once the activation has occurred however, CD45 shortens, allowing easier interactions and activation as an effector T helper cell.

Most silencers are constitutively expressed in organisms, only allowing activation of a gene by either inhibiting the silencer or by activating an enhancer region.

On activation of the indirect pathway, these inhibitory signals are reduced, which allows more activation of the subthalamic nucleus.

The products also allow remote activation of irrigation valves and other agriculture equipment (such as pumps and wind machines).

Work on the upper range lights commenced in 1885 and was completed in time to allow activation in January 1886.

This is known as an "inertia" chainbrake and will allow activation of the chainbrake even if the operator's left hand is not removed from the handle.

A regulatory binding site on the protein allows activation by phosphorylation, mainly by cAMP-dependent protein kinase.

This allows further activation of purinergic receptors and physiological responses such a spreading cytoplasmic waves of calcium.
