STRINGSTRING
SAP185 protein (Saccharomyces cerevisiae) - STRING interaction network
"SAP185" - 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

SAP185Protein 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)    
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)

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)

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)
       
 
  0.927
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)

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)

CDC25
Membrane bound guanine nucleotide exchange factor (GEF or GDP-release factor); indirectly regulates adenylate cyclase through activation of Ras1p and Ras2p by stimulating the exchange of GDP for GTP; required for progression through G1; Promotes the exchange of Ras-bound GDP by GTP. This protein positively controls the level of cellular cAMP at start, the stage at which the yeast cell division cycle is triggered (1589 aa)
     
 
  0.897
MDS3
Putative component of the TOR regulatory pathway; negative regulator of early meiotic gene expression; required, with Pmd1p, for growth under alkaline conditions; has an N-terminal kelch-like domain; Negatively regulates early sporulation-specific genes. Seems to exert its function by positively regulating the Ras/cAMP pathway. Required for growth under alkaline conditions. Acts synergetically with PMD1 (1487 aa)
       
 
  0.890
RTS3
Putative component of the protein phosphatase type 2A complex; May be a component of a protein phosphatase type 2A (PP2A) complex. Negatively regulates SIT4 phosphatase, a modulators of caffeine sensitivity (263 aa)
       
      0.868
UTP14
Subunit of U3-containing Small Subunit (SSU) processome complex involved in production of 18S rRNA and assembly of small ribosomal subunit; Involved in nucleolar processing of pre-18S ribosomal RNA (899 aa)
     
        0.845
HRK1
Protein kinase implicated in activation of the plasma membrane H(+)-ATPase Pma1p in response to glucose metabolism; plays a role in ion homeostasis; Involved in regulating the activity of the plasma membrane proton pump PMA1 (759 aa)
