STRINGSTRING
SAP4 protein (Saccharomyces cerevisiae) - STRING interaction network
"SAP4" - Protein required for function of the Sit4p protein phosphatase, member of a family of similar proteins that form complexes with Sit4p, including Sap155p, Sap185p, and Sap190p 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

SAP4Protein required for function of the Sit4p protein phosphatase, member of a family of similar proteins that form complexes with Sit4p, including Sap155p, Sap185p, and Sap190p; Associates with the SIT4 phosphatase in a cell cycle dependent manner. May be directly or indirectly involved in SIT4- dependent functions in budding and in normal G1 cyclin expression (By similarity) (818 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)

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)

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)
       
 
  0.750
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)
       
 
  0.719
MKC7
GPI-anchored aspartyl protease, member of the yapsin family of proteases involved in cell wall growth and maintenance; shares functions with Yap3p and Kex2p; Cleaves proteins C-terminally to the most C-terminal basic residue. Can process the alpha-mating factor precursor. Required for cell wall integrity (596 aa)
           
  0.697
SAP185
Protein that forms a complex with the Sit4p protein phosphatase and is required for its function; member of a family of similar proteins including Sap4p, Sap155p, and Sap190p; Associates with the SIT4 phosphatase in a cell cycle dependent manner. May be directly or indirectly involved in SIT4- dependent functions in budding and in normal G1 cyclin expression (1058 aa)
       
 
0.693
SAP190
Protein that forms a complex with the Sit4p protein phosphatase and is required for its function; member of a family of similar proteins including Sap4p, Sap155p, and Sap185p; Positive regulator of protein phosphatase SIT4. Involved in the general amino acid control (GAAC) response regulated by TOR. Involved in the dephosphorylation of the elongator complex subunit IKI3 (1033 aa)

TCO89
Subunit of TORC1 (Tor1p or Tor2p-Kog1p-Lst8p-Tco89p), a complex that regulates growth in response to nutrient availability; cooperates with Ssd1p in the maintenance of cellular integrity; deletion strains are hypersensitive to rapamycin; Component of TORC1, which regulates multiple cellular processes to control cell growth in response to environmental signals. Nutrient limitation and environmental stress signals cause inactivation of TORC1. Active TORC1 positively controls ribosome biogenesis via control of rRNA, ribosomal protein and tRNA gene expression, and rRNA processing. TORC1 po [...] (799 aa)
