Function:Regulatory subunit of protein phospatase 6 (PP6). May function as a scaffolding PP6 subunit. Involved in the PP6-mediated dephosphorylation of NFKBIE opposing its degradation in response to TNF-alpha.,similarity:Belongs to the SAPS family.,subunit:Protein phospatase 6 (PP6) holoenzyme is proposed to be a heterotrimeric complex formed by the catalytic subunit, a SAPS domain-containing subunit (PP6R) and an ankyrin repeat-domain containing regulatory subunit (ARS). Interacts with PPP6C and NFKBIE. Interacts with ANKRD28.,tissue specificity:Ubiquitously expressed with strongest expression in the testis followed by liver, heart, kidney, brain and placenta.,
