Webthe PP1 catalytic subunit correlated with the previously reported protein phosphatase activity, but PP2A subunits did not. The data suggest that the decreased protein phosphatase activity at mid-pregnancy was due to a decline in expression of the catalytic subunits of PP1 rather than changes in expression of PP2A subunits. WebIt is found that protein phosphatase 1 regulatory inhibitor subunit 14C (PPP1R 14C) is upregulated in TNBC and relevant to poor prognosis in patients and suggested that PPP1R14C might be a potential therapeutic target. 1 PDF Primary cilia are WNT-transducing organelles whose biogenesis is controlled by a WNT-PP1 axis.
