During mitogenic stimulation, cells proliferate at a higher rate, which is primarily determined by an enhanced rate of protein synthesis. Among other mechanisms, the MAP kinase pathway of signal transduction is involved in this. Global protein synthesis may be regulated by many mechanisms involving various steps of protein synthesis, namely, initiation, elongation, and termination. Thus, many protein factors may be involved in the same. In the above process (mitogenic stimulation), the following factors are the portable targets:

A. elF - 2

B. eEF-1

C. S6 kinase

D. elF-4E BP

The correct answer is
