PPP1R8 PrEST Antigen

Protein function: 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. [The UniProt Consortium] Buffer: PBS and 1M Urea, pH 7.4.
