Cell. Biol. 24:5863-5874(2004). CC -!- FUNCTION: Inhibitor subunit of the major nuclear protein CC phosphatase-1 (PP-1). It has RNA-binding activity but does not CC cleave RNA and may target PP-1 to RNA-associated substrates. May CC also be involved in pre-mRNA splicing. Binds DNA and might act as CC a transcriptional repressor. Essential for cell proliferation and CC early embryonic development. CC -!- SUBUNIT: Interacts with phosphorylated CDC5L, SF3B1 and MELK. Part CC of the spliceosome (By similarity). Interacts with EED. Part of a CC complex consisting of PPP1R8, EED, HDAC2 and PP-1. CC -!- SUBCELLULAR LOCATION: Nucleus (By similarity). Nucleus; nuclear CC speckle (By similarity). Note=Mainly, but not exclusively, CC nuclear. CC -!- DOMAIN: Has a basic N- and C-terminal and an acidic central CC domain. CC -!- PTM: May be inactivated by phosphorylation on Ser-199 or Ser-204 CC (By similarity). CC -!- MISCELLANEOUS: Mice lacking Ppp1r8 display a retarded growth and CC embryonic lethality at E6.5, due to defects in proliferation rate. CC -!- SIMILARITY: Contains 1 FHA domain.
