Phosphorylates RPS6 in response to serum or EGF via an mTOR-independent mechanism and promotes translation initiation by facilitating assembly of the pre-initiation complicated. In response to insulin, phosphorylates EIF4B, improving EIF4B affinity for the EIF3 complicated and stimulating cap-dependent translation.
