General annotation (Comments)

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. Ref.4
Subunit structure	Protein phospatase 6 (PP6) holoenzyme is proposed to be a heterotrimeric complex formed of 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, ANKRD44 and ANKRD52. Ref.4 Ref.5
Subcellular location	Cytoplasm Ref.4 Ref.5.
Tissue specificity	Ubiquitous with higher expression in testis. Ref.4
Sequence similarities	Belongs to the SAPS family.
