From: The coupling of pathways and processes through shared components
Scenario | Result |
---|---|
An additional component is involved the uptake of X by one of the two pathways through a complex formation mechanism. | The additional component can control how signalling through X is divided between the two pathways. This may enhance signalling specificity. The degree of control the additional component has depends on the mechanism of complex formation. |
The shared component is involved in two downstream pathways which display switching behaviour. | Where uptake of the shared component is significant, the switching behaviour of one pathway may influence that of the other. This can result in either a specific ordering of activation, or coordinated activation, of the two pathways. |
One of the downstream components, and its complex with the shared component, is diffusible. | The shared component is spread across the domain. This results in uptake being significant across the domain, with the spatial distribution of the nondiffusible components also affected. |
