Protein phosphatase 1 regulatory inhibitor subunit 8; Inhibitor subunit of the major nuclear protein phosphatase-1 (PP-1). It has RNA-binding activity but does not cleave RNA and may target PP-1 to RNA-associated substrates. May also be involved in pre-mRNA splicing. Binds DNA and might act as a transcriptional repressor. Seems to be required for cell proliferation.
Synonyms: PPP1R8, PPP1R8p, hPPP1R8, Q12972, Q6ICT4 ...
