Activator of RNA decay, ARD 1, ARD1, Homolog of E.coli RNase E, NIPP 1, NIPP1, Nuclear inhibitor of protein phosphatase 1, Nuclear subunit of PP1, PPP1R8, Protein phosphatase 1 regulatory inhibitor subunit 8, Protein phosphatase 1 regulatory subunit 8, RNase E.
Inhibitor subunit of the major nuclear protein phosphatase 1 (PP1). It has RNA binding activity but does not cleave RNA and may target PP1 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.
