IP Use at 2-5 µg/mg of lysate.


  • 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.

    Lane 1 : HeLa whole cell lysate at 50 µg
    Lane 2 : HeLa whole cell lysate at 15 µg
    Lane 3 : HeLa whole cell lysate at 5 µg
    Lane 4 : 293T whole cell lysate at 50 µg

    developed using the ECL technique

    Predicted band size : 115 kDa
    Observed band size : 140 kDa (why is the actual band size different from the predicted?)

    Exposure time : 30 seconds
  • 1mg whole lysate from HeLa cells was immunoprecipitated using ab70809 at 3ug/mg of lysate (lane 1) or a control rabbit Ig (lane 2). For the subsequent western blot, 20% of the immunoprecipitate was loaded per lane, and probed with ab70809 at 1ug/ml. Detection: chemiluminescence with exposure time of 10 seconds.
