nutrient-replete oocytes inhibit C2 via S135 phosphorylation catalyzed by calcium/calmodulin-dependent protein kinase II. We now show that C2 phosphorylated at S135 binds 14-3-3zeta, thus preventing C2 dephosphorylation. Moreover, we determined that S135 dephosphorylation is catalyzed by protein phosphatase-1 (PP1), which directly binds C2. |

Three phosphorylation sites identified are Ser342, Ser367, and Ser403. In the present study, we identify protein phosphatase 1 (PP1) as a negative regulator in the p53 signaling pathway. PP1 directly interacts with Mdmx and specifically dephosphorylates Mdmx at Ser367. The dephosphorylation of Mdmx increases its stability and thereby inhibits p53 activity. |

Moreover, IRBIT-associated PP1 specifically dephosphorylated Ser68 of IRBIT. Phosphorylation of Ser68 was required for subsequent phosphorylation of Ser71 and Ser74, but the latter two sites were not targeted by PP1. We found that phosphorylation of Ser71 and Ser74 were sufficient to enable inhibition of IP3 binding to the IP3R|Given the importance of phosphorylation for the function of IRBIT in suppressing IP3R activity [7,10], in the present study, we searched for a protein phosphatase involved in the dephosphorylation and, hence, inactivation of IRBIT. We found that IRBIT contains a specific well-conserved binding site for PP1. |

Dephosphorylation of eIF2α is central to ISR signal termination to restore protein synthesis and normal cell functioning. It is mediated by protein phosphatase 1 (PP1) complex that recruits a PP1 catalytic subunit (PP1c) and one of the two regulatory subunits. In mammals, phosphatase activity is regulated by either PPP1R15A (also known as growth arrest and DNA damageâ€inducible protein, GADD34), which is induced as part of the ISR. the GADD34–PP1 complex acts as an important negative feedback loop to restore protein synthesis once the ER stress has been resolved, and as such aids in cell survival |
