    text
  • found concentrated in cilia of epithelial cells, and was localized to cilia early in the process of formation, prior to the full acetylation of microtubules
    • basic FUNCTION
  • inhibitor subunit of protein phosphatase 1, involved in mammalian cell division
  • acts to enhance Aurora B by inhibiting specific PPP1CA holoenzymes that dephosphorylate Aurora B substrates necessary for chromosome segregation and cytokinesis
  • localizes to the primary cilium where it affects both Ser/Thr phosphorylation and is required for full tubulin acetylation
  • as a multifunctional protein, may link cell cycle progression to structure and stability of the primary cilium
  • major serine/threonine-phosphatase whose activity is dependent on its binding to regulatory subunits known as PP1 interacting proteins (PIPs), responsible for targeting PP1 to a specific cellular location, specifying its substrate or regulating its action
