We report here that posh is a direct substrate for phosphorylation by akt in vivo and in vitro, and we identify a major site of akt phosphorylation as serine 304 of posh, which lies within the rac-binding domain. We further show that phosphorylation of posh results in a decreased ability to bind activated rac, as does phosphomimetic s304d and s304e mutation of posh. |

Overexpression of posh induces apoptosis in a variety of cell types, but apoptosis can be prevented by co-expressing the pro-survival protein kinase akt. We report here that posh is a direct substrate for phosphorylation by akt in vivo and in vitro, and we identify a major site of akt phosphorylation as serine 304 of posh, which lies within the rac-binding domain. We further show that phosphorylation of posh results in a decreased ability to bind activated rac |

We find that posh and jips directly associate with one another to form a multiprotein complex, pjac (posh-jip apoptotic complex), that includes all of the known kinase components of the pathway. Our observations indicate that this complex is required for jnk activation and cell death in response to apoptotic stimuli. |
