“…Among these proteins, due to the fact of their pleiotropic roles in the dynamic regulation of protein function and cellular distribution, enzymes involved in dephosphorylation processes and, in particular protein phosphatase 1 (PP1), are of interest. PP1 is among the most active drivers of protein dephosphorylation [2]. In humans, there are three PP1 catalytic (PP1c) isoforms expressed by three distinct genes [3]; however, Plasmodium spp.…”

“…Hence, it is reasonable to expect that acting on PP1c interactions or interactors in Plasmodium may lead to the development of selective drugs. In yeast and mammals, PP1c has been shown to function almost exclusively in complexes [7][8][9][10] with diverse regulators/partners to dephosphorylate a plethora of proteins involved in many cellular processes including glycogen metabolism, transcription or mitosis [2]. So far, hundreds of partners have been reported, and many of them have been shown to be involved in the coordination of PP1c activities.…”

“…Previous studies revealed that the RVXF motif and T73 phosphorylation were required for PPP1R14C to bind and inhibit PP1, respectively 34–36 (Figure 5D). IP assays using antibodies against PPP1R14C demonstrated that p‐PPP1R14C/PP1/p‐GSK3β‐Ser9 formed a complex in TNBC cells (Figure 5E).…”

“…Studies have indicated that PPP1R14C regulates the protein activity depending on its inhibitory effect on PP1, and thus modulates the biological activities of numerous key proteins 20,27,34 . Dedinszki et al.…”

“…Indeed, inhibiting PP1 using RNAi or pharmacological inhibitors triggers MYC hyperphosphorylation, leading to chromatin eviction and MYC protein degradation (Dingar et al, 2018). Exploiting this PP1:PNUTS-MYC regulatory axis to target MYC destruction has promise; however, inhibiting PP1 catalytic activity is not a viable approach as PP1 has several protein substrates (Bollen et al, 2010;Casamayor and Arino, 2020;Cohen, 2002). Thus, to advance our understanding of how MYC is regulated by this phosphatase complex and to evaluate the potential for pharmacological disruption of MYC interaction with PP1:PNUTS to promote MYC degradation, we sought to delineate the molecular basis of this interaction.…”
