STRINGSTRING
SAP190 protein (Saccharomyces cerevisiae) - STRING interaction network
"SAP190" - 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

SAP190Protein 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)    
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)

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)

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)

SSD1
Translational repressor with a role in polar growth and wall integrity; regulated by Cbk1p phosphorylation to effect bud-specific translational control and localization of specific mRNAs; interacts with TOR pathway components; contains a functional /.../inal nuclear localization sequence and nucleocytoplasmic shuttling appears to be critical to Ssd1p function; Can suppress the lethality due to deletion of SIT4, and partially the defects due to BCY1 disruption. Is implicated in the control of the cell cycle G1 phase (1250 aa)

ZDS2
Protein with a role in regulating Swe1p-dependent polarized growth; interacts with Cdc55p; interacts with silencing proteins at the telomere; implicated in the mitotic exit network through regulation of Cdc14p localization; paralog of Zds1p; Acts as a negative regulator of polarized growth via an alternative mechanism to ZDS1. In heat-stressed cells appears to play a role in localizing BCY1 to the cytoplasm. Seems to interact with, and down-regulate, CDC42. Also acts as a suppressor of PKC1. May act as an integration point for distinct signaling pathways helping to maintain a balance a [...] (942 aa)

ARP7
Component of both the SWI/SNF and RSC chromatin remodeling complexes; actin-related protein involved in transcriptional regulation; Component of the chromatin structure remodeling complex (RSC), which is involved in transcription regulation and nucleosome positioning. RSC is responsible for the transfer of a histone octamer from a nucleosome core particle to naked DNA. The reaction requires ATP and involves an activated RSC-nucleosome intermediate. Remodeling reaction also involves DNA translocation, DNA twist and conformational change. As a reconfigurer of centromeric and flanking nuc [...] (477 aa)

RRD1
Peptidyl-prolyl cis/trans-isomerase; activator of the phosphotyrosyl phosphatase activity of PP2A; involved in G1 phase progression, microtubule dynamics, bud morphogenesis and DNA repair; required for rapid reduction of Sgs1p levels in response to /.../cin; subunit of the Tap42p-Sit4p-Rrd1p complex; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Acts as a regulatory subunit for TAP42-associated PP2A-like phosphatases modulating their activity or substrate specificity, probably by inducing a confor [...] (393 aa)

DIG1
MAP kinase-responsive inhibitor of the Ste12p transcription factor, involved in the regulation of mating-specific genes and the invasive growth pathway; related regulators Dig1p and Dig2p bind to Ste12p; DIG1 and DIG2 are negative regulators of the filamentation and pheromone induced mating program. DIG1 and DIG2 inhibit the transcriptional activity of STE12 by direct protein- protein interaction. DIG1 colocalizes to promoters with STE12 and redistributes with it during induction of filamentation (by butanol) or mating (by pheromone) to program specific genes, but binding of DIG1 to ST [...] (452 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)
