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 Size
small protein node
small nodes:
protein of unknown 3D structure
large protein node
large nodes:
some 3D structure is known or predicted
Node Color
colored protein node
colored nodes:
query proteins and first shell of interactors
non-colored protein node
white nodes:
second shell of interactors
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
database edge
from curated databases
experiment edge
experimentally determined
Predicted Interactions
neighborhood edge
gene neighborhood
fusion edge
gene fusions
cooccurrence edge
gene co-occurrence
Others

Your Input:
UQCRC1ubiquinol-cytochrome c reductase core protein I; This is a component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain. This protein may mediate formation of the complex between cytochromes c and c1 (480 aa)
DLDdihydrolipoamide dehydrogenase; Lipoamide dehydrogenase is a component of the glycine cleavage system as well as of the alpha-ketoacid dehydrogenase complexes. Involved in the hyperactivation of spermatazoa during capacitation and in the spermatazoal acrosome reaction (509 aa)
ACO2aconitase 2, mitochondrial; Catalyzes the isomerization of citrate to isocitrate via cis-aconitate (By similarity) (780 aa)
PASKPAS domain containing serine/threonine kinase; Serine/threonine-protein kinase involved in energy homeostasis and protein translation. Phosphorylates EEF1A1, GYS1, PDX1 and RPS6. Probably plays a role under changing environmental conditions (oxygen, glucose, nutrition), rather than under standard conditions. Acts as a sensor involved in energy homeostasis- regulates glycogen synthase synthesis by mediating phosphorylation of GYS1, leading to GYS1 inactivation. May be involved in glucose-stimulated insulin production in pancreas and regulation of glucagon secretion by glucose in alpha c [...] (1323 aa)
PMPCBpeptidase (mitochondrial processing) beta; Cleaves presequences (transit peptides) from mitochondrial protein precursors (By similarity) (489 aa)
SCLYselenocysteine lyase; Catalyzes the decomposition of L-selenocysteine to L- alanine and elemental selenium (By similarity) (453 aa)
IREB2iron-responsive element binding protein 2; RNA-binding protein that binds to iron-responsive elements (IRES), which are stem-loop structures found in the 5’- UTR of ferritin, and delta aminolevulinic acid synthase mRNAs, and in the 3’-UTR of transferrin receptor mRNA. Binding to the IRE element in ferritin results in the repression of its mRNA translation. Binding of the protein to the transferrin receptor mRNA inhibits the degradation of this otherwise rapidly degraded mRNA (963 aa)
EPAS1endothelial PAS domain protein 1; Transcription factor involved in the induction of oxygen regulated genes. Binds to core DNA sequence 5’-[AG]CGTG-3’ within the hypoxia response element (HRE) of target gene promoters. Regulates the vascular endothelial growth factor (VEGF) expression and seems to be implicated in the development of blood vessels and the tubular system of lung. May also play a role in the formation of the endothelium that gives rise to the blood brain barrier. Potent activator of the Tie-2 tyrosine kinase expression. Activation seems to require recruitment of transcript [...] (870 aa)
SDHAsuccinate dehydrogenase complex, subunit A, flavoprotein (Fp); Flavoprotein (FP) subunit of succinate dehydrogenase (SDH) that is involved in complex II of the mitochondrial electron transport chain and is responsible for transferring electrons from succinate to ubiquinone (coenzyme Q). Can act as a tumor suppressor (664 aa)
FREM2FRAS1 related extracellular matrix protein 2; Extracellular matrix protein required for maintenance of the integrity of the skin epithelium and for maintenance of renal epithelia. May be required for epidermal adhesion (3169 aa)
SLC25A33solute carrier family 25 (pyrimidine nucleotide carrier), member 33; Probable mitochondrial transporter which participates in dendritic cell endocytosis. May associate with mitochondrial oxidative phosphorylation (321 aa)
ACO1aconitase 1, soluble; Iron sensor. Binds a 4Fe-4S cluster and functions as aconitase when cellular iron levels are high. Functions as mRNA binding protein that regulates uptake, sequestration and utilization of iron when cellular iron levels are low. Binds to iron-responsive elements (IRES) in target mRNA species when iron levels are low. Binding of a 4Fe-4S cluster precludes RNA binding (889 aa)
ISCUiron-sulfur cluster scaffold homolog (E. coli); Involved in the assembly or repair of the [Fe-S] clusters present in iron-sulfur proteins. Binds iron (167 aa)
SLC25A36solute carrier family 25 (pyrimidine nucleotide carrier ), member 36 (311 aa)
UBCubiquitin C (685 aa)
ETFBelectron-transfer-flavoprotein, beta polypeptide; The electron transfer flavoprotein serves as a specific electron acceptor for several dehydrogenases, including five acyl- CoA dehydrogenases, glutaryl-CoA and sarcosine dehydrogenase. It transfers the electrons to the main mitochondrial respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase) (346 aa)
ARNTaryl hydrocarbon receptor nuclear translocator; Required for activity of the Ah (dioxin) receptor. This protein is required for the ligand-binding subunit to translocate from the cytosol to the nucleus after ligand binding. The complex then initiates transcription of genes involved in the activation of PAH procarcinogens. The heterodimer with HIF1A or EPAS1/HIF2A functions as a transcriptional regulator of the adaptive response to hypoxia (789 aa)
SLC25A28solute carrier family 25 (mitochondrial iron transporter), member 28; Mitochondrial iron transporter that mediates iron uptake. Probably required for heme synthesis of hemoproteins and Fe-S cluster assembly in non-erythroid cells. The iron delivered into the mitochondria, presumably as Fe(2+), is then probably delivered to ferrochelatase to catalyze Fe(2+) incorporation into protoprophyrin IX to make heme (By similarity) (364 aa)
NFS1NFS1 nitrogen fixation 1 homolog (S. cerevisiae); Catalyzes the removal of elemental sulfur from cysteine to produce alanine. It supplies the inorganic sulfur for iron- sulfur (Fe-S) clusters. May be involved in the biosynthesis of molybdenum cofactor (457 aa)
SDHBsuccinate dehydrogenase complex, subunit B, iron sulfur (Ip); Iron-sulfur protein (IP) subunit of succinate dehydrogenase (SDH) that is involved in complex II of the mitochondrial electron transport chain and is responsible for transferring electrons from succinate to ubiquinone (coenzyme Q) (280 aa)
FXNfrataxin; Promotes the biosynthesis of heme and assembly and repair of iron-sulfur clusters by delivering Fe(2+) to proteins involved in these pathways. May play a role in the protection against iron-catalyzed oxidative stress through its ability to catalyze the oxidation of Fe(2+) to Fe(3+); the oligomeric form but not the monomeric form has in vitro ferroxidase activity. May be able to store large amounts of iron in the form of a ferrihydrite mineral by oligomerization; however, the physiological relevance is unsure as reports are conflicting and the function has only been shown usin [...] (210 aa)
MIPEPmitochondrial intermediate peptidase; Cleaves proteins, imported into the mitochondrion, to their mature size (713 aa)
FECHferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX (By similarity) (429 aa)
SLC25A37solute carrier family 25 (mitochondrial iron transporter), member 37; Mitochondrial iron transporter that specifically mediates iron uptake in developing erythroid cells, thereby playing an essential role in heme biosynthesis. The iron delivered into the mitochondria, presumably as Fe(2+), is then probably delivered to ferrochelatase to catalyze Fe(2+) incorporation into protoprophyrin IX to make heme (By similarity) (338 aa)
LYRM4LYR motif containing 4; Required for nuclear and mitochondrial iron-sulfur protein biosynthesis (130 aa)
ETFAelectron-transfer-flavoprotein, alpha polypeptide; The electron transfer flavoprotein serves as a specific electron acceptor for several dehydrogenases, including five acyl- CoA dehydrogenases, glutaryl-CoA and sarcosine dehydrogenase. It transfers the electrons to the main mitochondrial respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase) (333 aa)
