STRINGSTRING
CDC55 protein (Saccharomyces cerevisiae) - STRING interaction network
"CDC55" - Non-essential regulatory subunit B of protein phosphatase 2A 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

CDC55Non-essential regulatory subunit B of protein phosphatase 2A (PP2A); localization to cytoplasm requires Zds1p and Zds2p and promotes mitotic entry; localization to nucleus prevents mitotic exit; required for correct nuclear division and chromosome segregation in meiosis; maintains nucleolar sequestration of Cdc14p during early meiosis; limits formation of PP2A-Rts1p holocomplexes to ensure timely dissolution of sister chromosome cohesion; homolog of mammalian B55; Phosphatase 2A affects a variety of biological processes in the cell such as transcription, cell cycle progression and cell [...] (526 aa)    
Predicted Functional Partners:
TPD3
Regulatory subunit A of the heterotrimeric protein phosphatase 2A (PP2A), which also contains regulatory subunit Cdc55p and either catalytic subunit Pph21p or Pph22p; required for cell morphogenesis and transcription by RNA polymerase III; Phosphatase 2A affects a variety of biological processes in the cell such as transcription, cell cycle progression and cellular morphogenesis, and provides an initial identification of critical substrates for this phosphatase. The regulatory subunit may direct the catalytic subunit to distinct, albeit overlapping, subsets of substrates (635 aa)
     
  0.999
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)
     
  0.999
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)
     
  0.999
RTS1
B-type regulatory subunit of protein phosphatase 2A (PP2A); Rts1p and Cdc55p are alternative regulatory subunits for PP2A; PP2A-Rts1p protects cohesin when recruited by Sgo1p to the pericentromere; highly enriched at centromeres in absence of Cdc55p /.../log of the mammalian B’ subunit of PP2A; The B regulatory subunit might modulate substrate selectivity and catalytic activity, and also might direct the localization of the catalytic enzyme to a particular subcellular compartment (757 aa)
     
  0.997
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)
     
  0.997
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)
     
  0.997
NET1
Core subunit of the RENT complex, which is a complex involved in nucleolar silencing and telophase exit; stimulates transcription by RNA polymerase I and regulates nucleolar structure; Has a role in chromosome maintenance and is involved in mitotic exit. Inhibits the action of CDC14 by sequestering it in the nucleolus. Also binds to RNA polymerase I and stimulates rRNA synthesis. Influences RDNA chromatin by tethering SIR2 to rDNA in the nucleolus (1189 aa)

SLK19
Kinetochore-associated protein required for normal segregation of chromosomes in meiosis and mitosis; component of the FEAR regulatory network, which promotes Cdc14p release from the nucleolus during anaphase; potential Cdc28p substrate; Has a role in spindle assembly and stability. Required to ensure a timely exit form mitosis. Essential to maintain pre- anaphase spindle polarity. Associates to the plus ends of the microtubules at the kinetochore and spindle midzone. A component of the FEAR (CDC14 Early Anaphase Release) network which promotes CDC14 release from the nucleolus during e [...] (821 aa)
       
  0.986
CDC28
Catalytic subunit of the main cell cycle cyclin-dependent kinase (CDK); alternately associates with G1 cyclins (CLNs) and G2/M cyclins (CLBs) which direct the CDK to specific substrates; This protein is essential for the completion of the start, the controlling event, in the cell cycle. More than 200 substrates have been identified (298 aa)

GLC7
Type 1 serine/threonine protein phosphatase catalytic subunit, involved in many processes (eg- glycogen metabolism, sporulation, mitosis); accumulates at mating projections by interaction with Afr1p; interacts with many regulatory subunits; Involved in control of glycogen metabolism, meiosis, translation, chromosome segregation, cell polarity and G2/M cell cycle progression. PP1 may act in opposition to the IPL1 protein kinase in regulating chromosome segregation by dephosphorylating H3S10ph. The BUD14-GLC7 complex is necessary to regulate microtubule dynamics at the cortex and may fun [...] (312 aa)
