PPM1B - protein phosphatase, Mg2+/Mn2+ dependent 1B Gene
Also Known as PP2CB; PP2CBETA; PP2C-beta; PPC2BETAX; PP2C-beta-X
Species: Homo sapiens
About PPM1B
This gene has 11 transcripts (splice variants), 202 orthologues, 16 paralogues and is associated with 1 phenotype. Ubiquitous expression in fat (RPKM 9.6), brain (RPKM 8.7) and 25 other tissues.
Summary
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, Jul 2008]
