Which of the following effects is least likely to be mediate

Which of the following effects is least likely to be mediated by a scaffolding protein ?

A Increase the local concentration of signaling components.

B Increase allosteric effects and cooperative binding of second messengers to their targets.

C Regulate the order in which a series of kinases can become activated following receipt of a signal.

D Decrease likelihood of crosstalk between signaling pathways that share a common kinase.

E Allow rapid negative feedback of a signaling response.

Solution

B Increase allosteric effects and cooperative binding of second messengers to their targets...... seems to be most appropriate/ least likely action of scafolding protien.

Scaffolding is done usually by scaffolding protiens in biological pathways/signals... but homotropic coperativity or allosteric regulation is a protiens internal property and has nothing to do with scaffolding protiens usually .

Hope it helps.
