Receptor-activated calcium channels (e.g., P2X purinergic receptors) open when a ligand binds to the channel, whereas store-operated calcium channels (e.g., transient receptor potential (TRP)) and archetype calcium release-activated channels (CRAC) are activated when the level of Ca2+ within the lumen of the ER decreases below a threshold level.
Some motion-activated alarms are pressure sensitive, so they are activated when the cat touches them or what they are positioned under.
Generally, transcription factor activities of ARFs are modulated by post-transcriptional regulation; ARF activity is inhibited by conjugation of AUX/IAA proteins and the ARFs are activated when the auxin level in the cell is elevated and the increased auxin induces degradation of the conjugated AUX/IAAs [ 92].
