STRINGSTRING
SAP155 protein (Saccharomyces cerevisiae) - STRING interaction network
"SAP155" - Protein that forms a complex with the Sit4p protein phosphatase and is required for its function in Saccharomyces cerevisiae
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

SAP155Protein that forms a complex with the Sit4p protein phosphatase and is required for its function; member of a family of similar proteins including Sap4p, Sap185p, and Sap190p; Positive regulator of protein phosphatase SIT4. Involved in directing expression of TOR-repressed genes and in dephosphorylation of NPR1 in response to nutrient starvation. Negatively modulates K(+) efflux of the cell by the Na(+)- K(+)/H(+) antiporter NHA1 (1002 aa)    
Predicted Functional Partners:
SIT4
Type 2A-related serine-threonine phosphatase that functions in the G1/S transition of the mitotic cycle; cytoplasmic and nuclear protein that modulates functions mediated by Pkc1p including cell wall and actin cytoskeleton organization; Involved in the dephosphorylation of the large subunit of RNA polymerase II. Is required in late G1 for normal G1 cyclin expression, bud initiation and expression of certain genes that are periodically expressed during late G1. Associates with the SAP proteins in a cell cycle-dependent manner (311 aa)
       
 
  0.991
PPH3
Catalytic subunit of protein phosphatase PP4 complex; Pph3p and Psy2p form active complex, Psy4p may provide substrate specificity; regulates recovery from the DNA damage checkpoint, the gene conversion- and single-strand annealing-mediated pathways of meiotic double-strand break repair and efficient Non-Homologous End-Joining (NHEJ) pathway; involved in activation of Gln3p to alleviate nitrogen catabolite repression; Pph3p and Psy2p localize to foci on meiotic chromosomes; Forms the histone H2A phosphatase complex in association with the regulatory subunits PSY2 and PSY4, which dephos [...] (308 aa)
       
 
  0.917
PPH21
Catalytic subunit of protein phosphatase 2A (PP2A), functionally redundant with Pph22p; methylated at C terminus; forms alternate complexes with several regulatory subunits; involved in signal transduction and regulation of mitosis; Exact function not known, phosphatase 2A performs an essential cellular function (369 aa)
       
 
  0.911
TIP41
Protein that interacts physically and genetically with Tap42p, which regulates protein phosphatase 2A; component of the TOR (target of rapamycin) signaling pathway; Involved in negative regulation of the TOR signaling pathway in response to type of available nitrogen source. Indirectly activates the PP2A phosphatase SIT4 via interaction with its suppressor TAP42. This interaction is enhanced under nitrogen limitation conditions. Also has a role in regulation of NPR1 in response to nitrogen limitation (356 aa)
       
 
  0.906
PPH22
Catalytic subunit of protein phosphatase 2A (PP2A), functionally redundant with Pph21p; methylated at C terminus; forms alternate complexes with several regulatory subunits; involved in signal transduction and regulation of mitosis; Exact function not known, phosphatase 2A performs an essential cellular function (377 aa)
       
 
  0.900
PPZ2
Serine/threonine protein phosphatase Z, isoform of Ppz1p; involved in regulation of potassium transport, which affects osmotic stability, cell cycle progression, and halotolerance; Essential for the maintenance of cell size and integrity in response to osmotic stress (710 aa)
       
 
  0.899
SDS24
One of two S. cerevisiae homologs (Sds23p and Sds24p) of the S. pombe Sds23 protein, which is implicated in APC/cyclosome regulation; involved in cell separation during budding; may play an indirect role in fluid-phase endocytosis; Involved in DNA replication and cell separation during budding (527 aa)
     
 
  0.859
ADE17
Enzyme of ’de novo’ purine biosynthesis containing both 5-aminoimidazole-4-carboxamide ribonucleotide transformylase and inosine monophosphate cyclohydrolase activities, isozyme of Ade16p; ade16 ade17 mutants require adenine and histidine (592 aa)
       
      0.806
SDS23
One of two S. cerevisiae homologs (Sds23p and Sds24p) of the S. pombe Sds23 protein, which is implicated in APC/cyclosome regulation; involved in cell separation during budding; Involved in DNA replication and cell separation during budding (527 aa)
     
 
  0.788
CMP2
Calcineurin A; one isoform (the other is CNA1) of the catalytic subunit of calcineurin, a Ca++/calmodulin-regulated protein phosphatase which regulates Crz1p (a stress-response transcription factor), the other calcineurin subunit is CNB1; Calcium-dependent, calmodulin-stimulated protein phosphatase. This subunit may have a role in the calmodulin activation of calcineurin (604 aa)
