PPP1CC Antibody

1. Here the authors show how Ki-67 and RepoMan form mitotic exit phosphatases by recruiting PP1, how they distinguish between distinct PP1 isoforms and how the assembly of these two holoenzymes are dynamically regulated by Aurora B kinase during mitosis. PMID: 27572260
2. Data suggest that PPP1CC catalyzes hydrolysis of an assortment of substrates (aryl methylphosphonates, fluorophosphate esters, phosphorothioate esters, phosphodiesters); conservative mutation of R221 to K results in a mutant that is more effective catalyst toward monoanionic substrates; PPP1CC does not catalyze the hydrolysis of a sulfate ester, which is unexpected. PMID: 28678475
3. PP1gamma is upregulated in hepatocellular carcinoma (HCC) cell lines and HCC specimens and promotes cancer cell proliferation through regulation of p53. High expression of PP1gamma in HCC cells contributed to doxorubicin resistance. PMID: 27921263
4. knock-down of PP1gamma alleviates glioma proliferation by reducing p65 transportation into the nucleus. PMID: 26936744
5. PP1gamma may be a novel target of the HPV-16 oncoproteins and indicate that it might be a potential novel biomarker for HPV-16 induced malignancy. PMID: 25886518
6. Although no obvious defects in the progression of mitosis were observed, the timing of dephosphorylation of the mutant Ki67 in anaphase was delayed, indicating that Ki67 itself is one of the substrates of PP1gamma-Ki67. PMID: 25012651
7. the lipin-1 N-terminal domain is important for its catalytic activity, nuclear localization, and binding to PP-1cgamma PMID: 24558042
8. Protein phosphatase 1gamma promotes the alternative splicing of CaMKIIdelta through its interaction with alternative splice factor. PMID: 24196533
9. When the Px(T)PxR motif is deleted or mutated via insertion of a phosphorylation site mimic (T311D), PP-1c fails to bind to all three ASPP proteins, ASPP1, ASPP2 and iASPP. PMID: 23088536
10. Depletion of PP1gamma enhances the localization of the SMN complex and snRNPs to Cajal bodies. PMID: 22454514
11. NUAK1 and PPP1CC are identified as positional candidate loci for skeletal muscle strength phenotypes. PMID: 21750233
12. The counteracting Nek2A and PP1gamma activities on the centrosome linker are controlled by Plk1. PMID: 21723128
13. The ataxia telangiectasia, mutated and Rad3-related-Chk1 axis regulates H3-pThr 11 dephosphorylation on DNA damage, at least in part by the activation of PP1gamma through Chk1-dependent inhibition of cyclin dependent kinases. PMID: 20948546
14. gamma isoform of the human protein phosphatase-1 catalytic subunit (PP1c gamma) as a high affinity in vitro target of phosphatidic acid PMID: 11856740
15. Nek2.PP1C complex is regulated by Inh2 via inhibition of phosphatase activity to initiate centrosome separation PMID: 12221103
16. Tat might function as a nuclear regulator of PP1 and interaction of Tat with PP1 is critical for activation of HIV-1 transcription by Tat PMID: 16131488
17. analysis of novel phosphatidic acid (PA) binding region on PP1c gamma that contains a unique loop-strand structural fold responsible for the interaction with PA PMID: 16201749
18. crystal structures of the cyanotoxins, motuporin (nodularin-V) and dihydromicrocystin-LA bound to human protein phosphatase-1c PMID: 16343532
19. We demonstrate that interaction with NIPP1 mediates decreased PP1gamma activity in hypoxia, an event which may constitute an inherent part of the cellular oxygen-sensing machinery and may play a role in physiologic adaptation to hypoxia. PMID: 16826568
20. Data show that URI and PP1gamma are components of an S6K1-regulated mitochondrial pathway dedicated to oppose sustained S6K1 survival signaling and to ensure that the threshold for apoptosis is set based on nutrient and growth factor availability. PMID: 17936702
21. Results describe a specific intracellular pathway involving the activation of PP1cgamma to mediate the effects of confluence-induced beta-catenin dephosphorylation. PMID: 17996206
22. PP1cgamma1 overexpression promotes VSMC survival by interfering with JNK1 and p53 phosphorylation cascades involved in apoptosis PMID: 18540044
