STRINGSTRING
FUB1 protein (Saccharomyces cerevisiae) - STRING interaction network
"FUB1" - Putative protein of unknown 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

FUB1Putative protein of unknown function; YCR076C is not an essential gene; Plays a role in the establishment of transcriptional silencing boundaries, preventing the propagation of heterochromatic silencing (250 aa)    
Predicted Functional Partners:
PUP3
Beta 3 subunit of the 20S proteasome involved in ubiquitin-dependent catabolism; human homolog is subunit C10; The proteasome degrades poly-ubiquitinated proteins in the cytoplasm and in the nucleus. It is essential for the regulated turnover of proteins and for the removal of misfolded proteins. The proteasome is a multicatalytic proteinase complex that is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. It has an ATP-dependent proteolytic activity. This subunit may participate in the trypsi [...] (205 aa)
       
      0.805
RTR2
Protein of unknown function with high similarity to Rtr1p; exhibits genetic interactions with Rtr1p; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm; YDR066C is not an essential gene; Probable RNA polymerase II subunit B1 C-terminal domain (CTD) phosphatase that regulates RNA polymerase II transcription. May have functional redundancy with RTR1 (196 aa)
           
  0.698
PRE2
Beta 5 subunit of the 20S proteasome, responsible for the chymotryptic activity of the proteasome; The proteasome degrades poly-ubiquitinated proteins in the cytoplasm and in the nucleus. It is essential for the regulated turnover of proteins and for the removal of misfolded proteins. The proteasome is a multicatalytic proteinase complex that is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. It has an ATP-dependent proteolytic activity. This unit is responsible of the chymotrypsin-like acti [...] (287 aa)
       
      0.676
RTR1
CTD phosphatase; dephosphorylates S5-P in the C-terminal domain of Rpo21p; has a cysteine-rich motif required for function and conserved in eukaryotes; shuttles between the nucleus and cytoplasm; RNA polymerase II subunit B1 C-terminal domain (CTD) phosphatase that dephosphorylates ’Ser-5’ of the CTD and regulates RNA polymerase II during the transition from ’Ser-5’ to ’Ser-2’ phosphorylation (226 aa)
           
  0.627
MXR2
Methionine-R-sulfoxide reductase, involved in the response to oxidative stress; protects iron-sulfur clusters from oxidative inactivation along with MXR1; involved in the regulation of lifespan; Methionine-R-sulfoxide reductase which catalyzes the reduction of methionine sulfoxide (MetSO) to methionine in proteins. Plays a protective role against oxidative stress by restoring activity to proteins that have been inactivated by methionine oxidation. Protects iron-sulfur clusters from oxidative inactivation along with MXR1. Involved in the regulation of lifespan (168 aa)
     
        0.622
MUB1
MYND domain-containing protein required for ubiquitination and turnover of Rpn4p; interacts with Ubr2p (E3) and indirectly with Rad6p (E2); short-lived protein degraded in a Ubr2p/Rad6p dependent manner; similar to the A. nidulans samB gene; Involved in the determination of the onset of polarized growth. Required for the ubiquitin-dependent degradation of RPN4. Cooperates with UBR2 to transfer ubiquitin from RAD6 to RPN4 (620 aa)
       
      0.507
CAD1
AP-1-like basic leucine zipper (bZIP) transcriptional activator involved in stress responses, iron metabolism, and pleiotropic drug resistance; controls a set of genes involved in stabilizing proteins; binds consensus sequence TTACTAA; Transcription activator closely related to YAP1. Like YAP1, its activity can be induced by cadmium and peroxide stress, probably involving similar mechanisms inducing nuclear accumulation and thus transcription activation. YAP2, like YAP1, preferentially binds to promoters with the core binding site 5’- TTA[CG]TAA-3’, but does not activate transcription [...] (409 aa)
           
  0.483
UMP1
Short-lived chaperone required for correct maturation of the 20S proteasome; may inhibit premature dimerization of proteasome half-mers; degraded by proteasome upon completion of its assembly; Short-lived chaperone present in the precursor form of the 20S proteasome and absent in the mature complex. Required for the correct assembly and enzymatic activation of the proteasome. Also prevents premature processing of the PRE2 propeptide (148 aa)

MPS1
Dual-specificity kinase required for spindle pole body (SPB) duplication and spindle checkpoint function; substrates include SPB proteins Spc42p, Spc110p, and Spc98p, mitotic exit network protein Mob1p, and checkpoint protein Mad1p; Involved in the regulation of the onset of mitosis. Involved in a pathway that coordinates cell proliferation and differentiation. Implicated in spindle pole body (SPD) duplication. Dual specificity kinase that can phosphorylate serine, threonine and tyrosine residues. Phosphorylates the SPC29 and SPC110 spindle pole body components (764 aa)

Subunit of RNAPII-associated chromatin remodeling Paf1 complex; regulates gene expression by directing cotranscriptional histone modification, influences transcription and chromatin structure through several independent functional domains; directly /.../irectly regulates DNA-binding properties of Spt15p and relative activities of different TATA elements; involved in transcription elongation as demonstrated by the G-less-based run-on (GLRO) assay; The PAF1 complex is a multifunctional complex. Involved in transcription initiation via genetic interactions with TATA- binding proteins. In [...] (558 aa)
