Interview Questions

regulation of cellular response of same pathway

Mechanisms of Signalling Network

Feedback Looping

Double Negative Feedback Looping

When 2 protein inhibit each other

Negative Feedback Looping

Pathyway inhibited by product produced by transcription activator of same pathway. End point is dampening & limiting of signalling.

Positive Feedback Looping

Signal from a protein activate 2nd protein which caused amplification & stabilization of signal

Multiple Diversions

Signal from a protein take different pathway from node, with one pathway regulating the other.

Gating

Pprimary Cascade that produce response is influenced through gate by other pathway (Secondary Cascade)

Coincidence Defection

2 Pathway Converge upon coincidence defector which caused response.
