PFAM accession number:PF04499
Interpro abstract (IPR007587):

This entry includes budding yeast Sit4-associated proteins, such as Sap155, Sap185, and Sap190. Sit4 is a phosphatase involved in a variety of processes including transcription, translation, bud formation, glycogen metabolism, monovalent ion homeostasis, H+ transport, and telomere function [ (PUBMED:16769727) ].

This entry also includes mammalian PP6 (Sit4 homologue)-associated proteins, such as PP6R1, PP6R2, and PP6R3 [ (PUBMED:16769727) ]. They are regulatory subunits of PP6 involved in the PP6-mediated dephosphorylation of NFKBIE opposing its degradation in response to TNF-alpha [ (PUBMED:16769727) ].

GO process:regulation of phosphoprotein phosphatase activity (GO:0043666)
GO function:protein phosphatase binding (GO:0019903)
