27041735 mutual regulatory mechanisms exist between PP4 and SAF-A. Interactions between PP4 and SAF-A played a role in prometaphase/metaphase transition.
25927939 These data suggested a potential role of PP4C in tumor progression.
25320307 Stathmin plays an essential role of in Merkel cell polyomavirus small tumor antigen-mediated microtubule destabilization and cell motility and this process is regulated by cellular phosphatase catalytic subunit of protein phosphatase 4.
24711418 PP4 and Wip1 are differentially required to counteract the p53-dependent cell cycle arrest in G1 and G2, by antagonizing early or late p53-mediated responses, respectively
24265311 Data indicate that the major phosphatase responsible for dephosphorylation of of BAF Ser-4 to be protein phosphatase 4 catalytic subunit.
23966160 Recombinant gamma-tubulin can be phosphorylated by Cdk1-cyclin B or Brsk1 and dephosphorylated by Ppp4c-R2-R3A in vitro.
23830831 PP4c is a key regulator of cortical development that changes the orientation of progenitor division responsible for the transition between symmetric and asymmetric cell division.
23671329 Results show PP4C as a fostriecin-sensitive phosphatase and demonstrate that the suppression of PP4C triggers mitotic slippage/apoptosis.
23084358 PP4R1 and PP4c Cooperate to Catalyze IKK Dephosphorylation
22732494 PP4C and KAP1 are in the same epistasis group, and PP4 is involved in NHEJ-mediated DSB repair, possibly through regulating the phosphorylation status of KAP1.
