STRINGSTRING
ROX1 protein (Saccharomyces cerevisiae) - STRING interaction network
"ROX1" - Heme-dependent repressor of hypoxic genes 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

ROX1Heme-dependent repressor of hypoxic genes; contains an HMG domain that is responsible for DNA bending activity; Transcription factor that represses the expression of HEM13, COX5B, ANB1, CYC7 or AAC3 (hypoxic function). Binds to the DNA sequence 5’-RRRTAACAAGAG-3’ (368 aa)    
Predicted Functional Partners:
MOT3
Nuclear transcription factor with two Cys2-His2 zinc fingers; involved in repression of a subset of hypoxic genes by Rox1p, repression of several DAN/TIR genes during aerobic growth, and repression of ergosterol biosynthetic genes; can form the [MOT /.../ion; Transcription factor that affects the expression of a large set of genes. Recognizes and binds to the consensus sequence 5’-[CAT]AGG[TC]A-3’ in the promoter region. Plays a major role in the repression of a specific subset of hypoxic genes (e.g. ANB1, DAN1 and HEM13) under aerobic conditions. Acts synergistically with the transcri [...] (490 aa)

CYC8
General transcriptional co-repressor, acts together with Tup1p; also acts as part of a transcriptional co-activator complex that recruits the SWI/SNF and SAGA complexes to promoters; can form the prion [OCT+]; Acts as component of the CYC8-TUP1 corepressor complex which is involved in the repression of many genes in a wide variety of physiological processes including heme-regulated and catabolite repressed genes. May also be involved in the derepression of at least some target genes. The complex is recruited to target genes by interaction with DNA-bound transcriptional repressors, like [...] (966 aa)

ANB1
Translation elongation factor eIF-5A, previously thought to function in translation initiation; similar to and functionally redundant with Hyp2p; undergoes an essential hypusination modification; expressed under anaerobic conditions; mRNA-binding protein involved in translation elongation. Has an important function at the level of mRNA turnover, probably acting downstream of decapping. Involved in actin dynamics and cell cycle progression, mRNA decay and probably in a pathway involved in stress response and maintenance of cell wall integrity. Essential for polarized growth, a process n [...] (157 aa)
           
  0.885
HEM13
Coproporphyrinogen III oxidase, an oxygen requiring enzyme that catalyzes the sixth step in the heme biosynthetic pathway; transcription is repressed by oxygen and heme (via Rox1p and Hap1p); Involved in the heme biosynthesis. Catalyzes the aerobic oxidative decarboxylation of propionate groups of rings A and B of coproporphyrinogen-III to yield the vinyl groups in protoporphyrinogen-IX (By similarity) (328 aa)
       
 
  0.877
EUG1
Protein disulfide isomerase of the endoplasmic reticulum lumen, function overlaps with that of Pdi1p; may interact with nascent polypeptides in the ER; Probably interacts with nascent polypeptides in the endoplasmic reticulum. It is an essential gene only in the absence of PDI. Its native disulfide isomerase activity is very low (517 aa)
       
 
  0.875
TUP1
General repressor of transcription, forms complex with Cyc8p, involved in the establishment of repressive chromatin structure through interactions with histones H3 and H4, appears to enhance expression of some genes; Acts as component of the CYC8-TUP1 corepressor complex which is involved in the repression of many genes in a wide variety of physiological processes including heme-regulated and catabolite repressed genes. May also be involved in the derepression of at least some target genes. The complex is recruited to target genes by interaction with DNA-bound transcriptional repressor [...] (713 aa)

UPC2
Sterol regulatory element binding protein, induces transcription of sterol biosynthetic genes and of DAN/TIR gene products; Ecm22p homolog; relocates from intracellular membranes to perinuclear foci on sterol depletion; Transcription factor that is involved in activation of anaerobic genes such as DAN/TIR cell wall mannoprotein genes and YML083c. Appears to bind to anaerobic response elements (AR1) with the consensus sequence 5’-TCGTTYAG-3’ present in the promoter regions of DAN/TIR genes. Involved in sterol uptake and regulation of the sterol biosynthesis. Binds to sterol regulatory e [...] (913 aa)

CYC7
Cytochrome c isoform 2, expressed under hypoxic conditions; electron carrier of the mitochondrial intermembrane space that transfers electrons from ubiquinone-cytochrome c oxidoreductase to cytochrome c oxidase during cellular respiration; Electron carrier protein. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain (113 aa)

IXR1
Protein that binds DNA containing intrastrand cross-links formed by cisplatin, contains two HMG (high mobility group box) domains, which confer the ability to bend cisplatin-modified DNA; mediates aerobic transcriptional repression of COX5b; Binds to platinated DNA and confers sensitivity to the anticancer drug cisplatin. Activate the expression of the COX5B gene (597 aa)

TAF2
TFIID subunit (150 kDa), involved in RNA polymerase II transcription initiation; Functions as a component of the DNA-binding general transcription factor complex TFIID. Binding of TFIID to a promoter (with or without TATA element) is the initial step in pre- initiation complex (PIC) formation. TFIID plays a key role in the regulation of gene expression by RNA polymerase II through different activities such as transcription activator interaction, core promoter recognition and selectivity, TFIIA and TFIIB interaction, chromatin modification (histone acetylation by TAF1), facilitation of [...] (1407 aa)
