ARR2 protein (Saccharomyces cerevisiae) - STRING interaction network
"ARR2" - Arsenate reductase required for arsenate resistance in Saccharomyces cerevisiae
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 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
protein homology

ARR2Arsenate reductase required for arsenate resistance; converts arsenate to arsenite which can then be exported from cells by Arr3p; Involved in resistance to arsenic compounds (130 aa)    
Predicted Functional Partners:
Plasma membrane metalloid/H+ antiporter; transports arsenite and antimonite; required for resistance to arsenic compounds; transcription is activated by Arr1p in the presence of arsenite; Plasma membrane transporter that confers resistance to toxic metalloids by mediating extrusion of arsenite (As(III)) and antimonite (Sb(III)) out of cells. Displays low-affinity As(III)/H(+) and Sb(III)/H(+) exchange activity (404 aa)
Protein kinase, required for cell-cycle arrest in response to DNA damage; activated by trans autophosphorylation when interacting with hyperphosphorylated Rad9p; also interacts with ARS1 and plays a role in initiation of DNA replication; Controls S-phase checkpoint as well as G1 and G2 DNA damage checkpoints. Phosphorylates proteins on serine, threonine, and tyrosine. Prevents entry into anaphase and mitotic exit after DNA damage via regulation of the Polo kinase CDC5. Seems to be involved in the phosphorylation of RPH1 (821 aa)
Cell-cycle checkpoint serine-threonine kinase required for DNA damage-induced transcription of certain target genes, phosphorylation of Rad55p and Sml1p, and transient G2/M arrest after DNA damage; also regulates postreplicative DNA repair; Transducer of the DNA damage signal. Phosphorylates SML1 on serine residues. Cooperates with the PAN deadenylation complex in the regulation of RAD5 mRNA levels and cell survival in response to replicational stress (513 aa)
Serine/threonine protein kinase, subunit of the transcription factor TFIIH; involved in transcription initiation at RNA polymerase II promoters; Catalytic component of the TFIIK complex (KIN28-CCL1 dimer) which is the protein kinase component of transcription factor IIH (TFIIH) and phosphorylates the C-terminal domain of RNA polymerase II during transition from transcription to elongation after preinitiation complex (PIC) formation, thereby positively regulating transcription. TFIIH (or factor B) is essential for both basal and activated transcription, and is involved in nucleotide exc [...] (306 aa)
Cyclin-dependent kinase, with ten cyclin partners; involved in regulating the cellular response to nutrient levels and environmental conditions and progression through the cell cycle; Cyclin-dependent protein kinase (CDK) catalytic subunit that regulates multiple cell cycle and metabolic processes in response to nutrient availability. Associates with different cyclins, that control kinase activity, substrate specificity and subcellular location of the kinase. Favorable growth conditions always result in activated cyclin-CDK complexes. Regulates metabolic processes when associated with [...] (305 aa)
Protein kinase implicated in activation of the plasma membrane H(+)-ATPase Pma1p in response to glucose metabolism; plays a role in ion homeostasis; Involved in regulating the activity of the plasma membrane proton pump PMA1 (759 aa)
Protein kinase that stabilizes several plasma membrane amino acid transporters by antagonizing their ubiquitin-mediated degradation; phosphorylates Aly2p; Nutrient-regulated protein kinase that promotes the activity of at least 6 distinct transport systems for nitrogenous nutrients under conditions of nitrogen catabolite derepression. Under poor nitrogen growth conditions, required for post-Golgi sorting of the general amino acid permease GAP1 and the three known ammonia permeases, MEP1/2/3, to the plasma membrane. Contributes also to the stability and the retention of GAP1 at the plas [...] (790 aa)
Putative serine/threonine protein kinase with unknown cellular role (724 aa)
Putative protein kinase; overexpression increases sodium and lithium tolerance, whereas gene disruption increases cation and low pH sensitivity and impairs potassium uptake, suggesting a role in regulation of Trk1p and/or Trk2p transporters; Protein kinase involved in salt tolerance and pH sensitivity, probably by regulating plasma membrane potential and cation influx. Positively controls the TRK1-TRK2 potassium transport system in response to potassium starvation. Stabilizes TRK1 in the plasma membrane by preventing its vacuolar sorting and degradation. Also stabilizes other plasma me [...] (855 aa)
Serine/threonine protein kinase that inhibits pheromone induced signalling downstream of MAPK, possibly at the level of the Ste12p transcription factor; mutant has increased aneuploidy tolerance; Protein kinase that functions as regulator in the pheromone-induced mating pathway downstream of mitogen-activated protein kinase (MAPK) FUS3. Diminishes transcriptional induction of genes in response to pheromone signaling (699 aa)
