Function
Targets myosin phosphatase to the actin cytoskeleton. Required for the regulation of the actin cytoskeleton by RhoA and ROCK1. Depletion leads to an increased number of stress fibers in smooth muscle cells through stabilization of actin fibers by phosphorylated myosin. Overexpression of MRIP as well as its F-actin-binding region leads to disassembly of stress fibers in neuronal cells.
Ppm1b prevents Rip3 auto-activation in resting cells.|Together, these data demonstrate that Ppm1b dephosphorylates Rip3 and thus negatively regulates TNF induced necroptosis in L929 cells.
