MAPK activates CREB kinase, which in turn phosphorylates and activates CREB. Purification, sequencing, and biochemical characterization of CREB kinase revealed that it is identical to a member of the pp90(RSK) family, RSK2. RSK2 was shown to mediate growth factor induction of CREB serine-133 phosphorylation both in vitro and in vivo. These findings identify a cellular function for RSK2 and define a mechanism whereby growth factor signals mediated by RAS and MAPK are transmitted to the nucleus to activate gene expression

In the present study, we demonstrate that RSK2 is associated in vivo with PP2Cdelta (protein phosphatase 2Cdelta).

Moreover, we found that rsk1/2 specifically phosphorylates kibra at two highly conserved sites (thr(929) and ser(947)) in vitro and in cells. Rsk-mediated phosphorylation is required for kibra binding to rsk1, but not rsk2.

The ribosomal S6 kinase 2 (RSK2) is a member of the p90 ribosomal S6 kinase (p90RSK) family of proteins and plays a critical role in proliferation, cell cycle, and cell transformation. Here, we report that RSK2 phosphorylates caspase-8, and Thr-263 was identified as a novel caspase-8 phosphorylation site. In addition, we showed that EGF induces caspase-8 ubiquitination and degradation through the proteasome pathway, and phosphorylation of Thr-263 is associated with caspase-8 stability.

The results showed that tyr-488 is a major site of src but mutations at tyr-529 or tyr-707 did not significantly decrease src-dependent tyrosine phosphorylation of rsk2 (fig. 4c). However, we have previously characterized the tyr-488 site that is also phosphorylated by fgfr3 (14), and substitution of tyr-488 did not affect rsk2 activation.

Together, our findings suggest that src-dependent phosphorylation at tyr-529 facilitates inactive erk binding to rsk2, which might be a general requirement for rsk2 activation by egf through the mek/erk pathway.

Epidermal growth factor stimulates rsk2 activation through activation of the mek/erk pathway and src-dependent tyrosine phosphorylation of rsk2 at tyr-529. By mass spectroscopy-based studies, we identified src tyrosine kinase family members src and fyn as upstream kinases of rsk2 tyr-529.

Upon truncation of this c-terminal stretch, or mutation of the tyr-707 residue alone, autoinhibition is attenuated, and the kinase becomes constitutively active. Based on these findings we propose that phosphorylation of the tyr-707 represents a novel alternative regulatory mechanism for p90rsk activation.

Phosphorylation at ser-11 (h3s10ph) by rps6ka4 and rps6ka5 is important during interphase because it enables the transcription of genes following external stimulation, like mitogens, stress, growth factors or uv irradiation and result in the activation of genes, such as c-fos and c-jun.
