Protein attributes
| Sequence length | 966 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
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.5 |
| Subunit structure | 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. Ref.5 Ref.6 |
| Subcellular location | |
| Tissue specificity | Ubiquitously expressed with strongest expression in the testis followed by liver, heart, kidney, brain and placenta. Ref.5 |
| Sequence similarities | Belongs to the SAPS family. |
| Sequence caution | The sequence BAA31660.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. |
