STRINGSTRING
MET18 protein (Saccharomyces cerevisiae) - STRING interaction network
"MET18" - DNA repair and TFIIH regulator, required for both nucleotide excision repair 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

MET18DNA repair and TFIIH regulator, required for both nucleotide excision repair (NER) and RNA polymerase II (RNAP II) transcription; involved in telomere maintenance; Key component of the cytosolic iron-sulfur protein assembly (CIA) machinery that mediates the incorporation of iron- sulfur cluster into apoproteins specifically involved in DNA metabolism and genomic integrity. Acts as an adapter between early-acting CIA components and a subset of cellular target iron- sulfur proteins such as RAD3/XPD and DNA2, thereby playing a key role in nucleotide excision repair (NER) and RNA polymeras [...] (1032 aa)    
Predicted Functional Partners:
CIA2
Protein of unknown function required for establishment of sister chromatid cohesion; synthetically lethal with RFC5, an RF-C subunit that links replication to cohesion establishment; YHR122W is an essential gene; May play a role in chromosome segregation through establishment of sister chromatid cohesion (231 aa)

CIA1
WD40 repeat protein involved in assembly of cytosolic and nuclear iron-sulfur proteins; similar to the human Ciao1 protein; YDR267C is an essential gene; Essential component of the cytosolic iron-sulfur (Fe/S) protein assembly machinery. Required for the maturation of extramitochondrial Fe/S proteins (330 aa)

RAD3
5’ to 3’ DNA helicase, involved in nucleotide excision repair and transcription; subunit of RNA polII initiation factor TFIIH and of Nucleotide Excision Repair Factor 3 (NEF3); homolog of human XPD protein; mutant has aneuploidy tolerance; ATP-dependent DNA helicase involved in excision repair of DNA damaged with UV light, bulky adducts, or cross-linking agents. Necessary for excision of pyrimidine dimers. Also unwinds DNA/RNA duplexes. Plays an essential role in the cell viability. Involved in the maintenance of the fidelity of DNA replication. Acts as component of the general transcr [...] (778 aa)

POL3
Catalytic subunit of DNA polymerase delta; required for chromosomal DNA replication during mitosis and meiosis, intragenic recombination, repair of double strand DNA breaks, and DNA replication during nucleotide excision repair (NER); DNA polymerase delta (DNA polymerase III) participates in chromosomal DNA replication. It is required during synthesis of the leading and lagging DNA strands at the replication fork and binds at/or near replication origins and moves along DNA with the replication fork. It has 3’-5’ proofreading exonuclease activity that correct errors arising during DNA r [...] (1097 aa)

NBP35
Essential cytoplasmic iron-sulfur cluster binding protein; forms a complex with Cfd1p that is involved in iron-sulfur protein assembly in the cytosol; similar to P-loop NTPases; Component of the cytosolic iron-sulfur (Fe/S) protein assembly (CIA) machinery. Required for maturation of extramitochondrial Fe-S proteins. The NBP35-CFD1 heterotetramer forms a Fe-S scaffold complex, mediating the de novo assembly of an Fe-S cluster and its transfer to target apoproteins. Required for biogenesis and export of both ribosomal subunits, which may reflect a role in assembly of the Fe/S clusters i [...] (328 aa)

DNA2
Tripartite DNA replication factor with single-stranded DNA-dependent ATPase, ATP-dependent nuclease, and helicase activities; required for Okazaki fragment processing; involved in DNA repair; cell-cycle dependent localization; Key enzyme involved in DNA replication and DNA repair. Involved in Okazaki fragments processing by cleaving long flaps that escape FEN1- flaps that are longer than 27 nucleotides are coated by replication protein A complex (RPA), leading to recruit DNA2 which cleaves the flap until it is too short to bind RPA and becomes a substrate for FEN1. Also involved in 5’- [...] (1522 aa)

NAR1
Component of the cytosolic iron-sulfur (FeS) protein assembly machinery, required for maturation of cytosolic and nuclear FeS proteins and for normal resistance to oxidative stress; homologous to human Narf; Essential component of a cytosolic Fe/S protein assembly machinery. Required for maturation of extramitochondrial Fe/S proteins. May play a role in the transfer of pre-assembled Fe/S clusters to target apoproteins (491 aa)

CFD1
Highly conserved iron-sulfur cluster binding protein; localized in the cytoplasm; forms a complex with Nbp35p that is involved in iron-sulfur protein assembly in the cytosol; Component of the cytosolic iron-sulfur (Fe/S) protein assembly (CIA) machinery. Required for maturation of extramitochondrial Fe-S proteins. The NBP35-CFD1 heterotetramer forms a Fe-S scaffold complex, mediating the de novo assembly of an Fe-S cluster and its transfer to target apoproteins.

AFT1
Transcription factor involved in iron utilization and homeostasis; binds the consensus site PyPuCACCCPu and activates the expression of target genes in response to changes in iron availability; Probable transcription factor that activates the genes for FRE1, FRE2 and FET3 in response to iron deprivation.
