Application Abreviews Notes

IHC-P Use at an assay dependent concentration.
WB 1/500 - 1/1000. Detects a band of approximately 130 kDa (predicted molecular weight: 115 kDa).


  • FunctionRegulates myosin phosphatase activity.
  • Tissue specificityExpressed in striated muscles, specifically in type 2a fibers (at protein level).
  • Sequence similaritiesContains 6 ANK repeats.
  • Developmental stageInduced by 2-fold during pregnancy, including in abdominus rectus muscle.
  • DomainHeterotetramerization is mediated by the interaction between a coiled-coil of PRKG1 and the leucine/isoleucine zipper of PPP1R12A/MBS, the myosin-binding subunit of the myosin phosphatase.
  • Post-translational
    Phosphorylated by CIT (Rho-associated kinase) (By similarity). Phosphorylated cooperatively by ROCK1 and CDC42BP on Thr-696. Phosphorylated on upon DNA damage, probably by ATM or ATR.
    In vitro, phosphorylation of Ser-695 by PKA and PKG appears to prevent phosphorylation of the inhibitory site Thr-696, probably mediated by PRKG1.
