STRINGSTRING
ESC2 protein (Saccharomyces cerevisiae) - STRING interaction network
"ESC2" - Sumo-like domain protein 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

ESC2Sumo-like domain protein; prevents accumulation of toxic intermediates during replication-associated recombinational repair; roles in silencing, lifespan, chromatid cohesion and the intra-S-phase DNA damage checkpoint; RENi family member; May be a substrate targeting component of a cullin-RING- based E3 ubiquitin-protein ligase complex RTT101(MMS1-ESC2). Involved in HMR and telomere silencing via the recruitment or stabilizing of the SIR (silent information regulators) complex (456 aa)    
Predicted Functional Partners:

RPN5
Subunit of the COP9 signalosome (CSN) and non-ATPase regulatory subunit of the 26S proteasome lid, similar to mammalian p55 subunit and to another S. cerevisiae regulatory subunit, Rpn7p; Rpn5p is an essential protein; Acts as a regulatory subunit of the 26S proteasome which is involved in the ATP-dependent degradation of ubiquitinated proteins (445 aa)

SRS2
DNA helicase and DNA-dependent ATPase involved in DNA repair, needed for proper timing of commitment to meiotic recombination and transition from Meiosis I to II; blocks trinucleotide repeat expansion; affects genome stability; ATP-dependent DNA helicase involved in DNA repair at least for UV-induced lesions. The polarity of the helicase activity was determined to be 3’ to 5’ (1174 aa)

SLX5
Subunit of the Slx5-Slx8 SUMO-targeted ubiquitin ligase (STUbL) complex, stimulated by SUMO-modified substrates; contains a RING domain and two SIMs (SUMO-interacting motifs); forms SUMO-dependent nuclear foci, including DNA repair centers; Mediates ubiquitination and subsequent desumoylation/degradation of sumoylated proteins and proteins containing SUMO-like domains. Promotes UBC4-dependent ubiquitination that mediates the proteolytic down-regulation of sumoylated proteins. Involved in the stimulation of ubiquitin conjugating enzymes, including UBC1, UBC4, UBC5 and UBC13-MMS2. Acts a [...] (619 aa)

SIR1
Protein involved in silencing at mating-type loci HML and HMR; recruitment to silent chromatin requires interactions with Orc1p and with Sir4p, through a common Sir1p domain; binds to centromeric chromatin; Involved in the establishment, but not the maintenance, of heterochromatic silencing at the cryptic mating-type loci HMR and HML. Is recruited by interacting with the ORC1 subunit of the origin recognition complex (ORC), which binds to HML-I or HMR-E silencers, DNA elements that direct the formation of silent chromatin at the mating-type loci. Establishes transcriptional silencing b [...] (654 aa)

SLX4
Endonuclease involved in processing DNA during recombination and repair; cleaves branched structures in a complex with Slx1p; involved in Rad1p/Rad10p-dependent removal of 3’-nonhomologous tails during DSBR via single-strand annealing; Regulatory subunit that interacts with and increases the activity of different structure-specific endonucleases.

The CRL associates with CDC34 as the E2 ubiquitin-conjugating enzyme. The functional specificity of the CRL depends on the type of the associated substrate receptor protein. RTT101(MMS1-MMS22) promotes fork progression t [...] (1407 aa)

MRC1
S-phase checkpoint protein required for DNA replication; interacts with and stabilizes Pol2p at stalled replication forks during stress, where it forms a pausing complex with Tof1p and is phosphorylated by Mec1p; protects uncapped telomeres; Required for normal DNA replication. Phosphorylated in response to DNA replication stress. Phosphorylation allows it to mediate the activation of RAD53 (1096 aa)
