Western blot analysis of PPM1B over-expressed 293 cell line, cotransfected with PPM1B Validated Chimera RNAi ( Cat # H00005495-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with PPM1B monoclonal antibody (M01), clone 1A3-2A4 (Cat # H00005495-M01 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
Proximity Ligation Analysis of protein-protein interactions between ARRB2 and PPM1B. HeLa cells were stained with anti-ARRB2 rabbit purified polyclonal 1:1200 and anti-PPM1B mouse monoclonal antibody 1:50. Each red dot represents the detection of protein-protein interaction complex, and nuclei were counterstained with DAPI (blue).
The protein encoded by this gene is a member of the PP2C family of Ser/Thr protein phosphatases. PP2C family members are known to be negative regulators of cell stress response pathways. This phosphatase has been shown to dephosphorylate cyclin-dependent kinases (CDKs), and thus may be involved in cell cycle control. Overexpression of this phosphatase is reported to cause cell-growth arrest or cell death. Alternative splicing results in multiple transcript variants encoding different isoforms. Additional transcript variants have been described, but currently do not represent full-length sequences. [provided by RefSeq
