CAP–cAMP increases the rate of formation of the closed promoter complex, CAP–cAMP provides CPC for conversion to the open promoter complex. 

Thus, the net effect of CAP–cAMP is to increase the rate of open promoter complex formation.

Orthograde transport

moves from the cell body toward the axon terminals 

occurs along microtubules that run along the length of the axon and requires dynein and kinesin
