Signal Integration
Captions available
The idea
Signal integration merges input from two or more cell-surface receptors so a cell produces one unified response only once every required signal is present.
In practice
A cell requiring both a growth factor and an adhesion signal before dividing integrates two pathways into one decision.
Where people slip
Signal integration requires combined input from multiple pathways, not one pathway merely running faster.
