In this study, it is shown that dephosphorylation of Tyr15 triggered activation of the pp34 - cyclin complex from fission yeast, that a human protein - tyrosine phosphatase can catalyze this event both in vitro and in vivo, and that activation of fission yeast pp34 does not require threonine dephosphorylation.
A widespread family of serine / threonine protein phosphatases shares a common regulatory switch with proteasomal proteases Bradshaw, N., et al., eLife doi: 10.7554 / eLife.26111.
More recently, we elucidated an additional mechanism of tumor suppression mediated by canonical ephrin - induced EphA2 signaling (Figure 1A), which leads to inhibition of the AKT - mTORC1 oncogenic pathway through interplay of EphA2 with a phosphatase that dephosphorylates the AKT serine / threonine kinase.
The balance between kinase and phosphatase activities determines the rate of phosphorylation of the insulin receptor kinase domain and several downstream targets including the phosphatidylinositol phosphates, the serine / threonine kinase Akt1 and the mTOR.
