CTR1 protein (Saccharomyces cerevisiae) - STRING interaction network
"CTR1" - High-affinity copper transporter of the plasma membrane, mediates nearly all copper uptake under low copper conditions 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
Your Input:
Gene Fusion
CTR1High-affinity copper transporter of the plasma membrane, mediates nearly all copper uptake under low copper conditions; transcriptionally induced at low copper levels and degraded at high copper levels; Required for high affinity copper (probably reduced Cu I) transport into the cell (406 aa)    
Predicted Functional Partners:
Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially/completely overlaps the verified ORF CTR (144 aa)
Ferro-O2-oxidoreductase required for high-affinity iron uptake and involved in mediating resistance to copper ion toxicity, belongs to class of integral membrane multicopper oxidases; Iron transport multicopper ferroxidase required for Fe(2+) ion high affinity uptake. Required to oxidize Fe(2+) and release it from the transporter. Essential component of copper- dependent iron transport (636 aa)
Putative low-affinity copper transporter of the vacuolar membrane; mutation confers resistance to toxic copper concentrations, while overexpression confers resistance to copper starvation; Provides bioavailable copper via mobilization of vacuolar copper stores and export to the cytoplasm (189 aa)
High-affinity copper transporter of the plasma membrane, acts as a trimer; gene is disrupted by a Ty2 transposon insertion in many laboratory strains of S. cerevisiae; Required for high affinity copper (probably reduced Cu I) transport into the cell (241 aa)
Component of the Paf1p complex; binds to and modulates the activity of RNA polymerases I and II; required for expression of certain genes, modification of some histones, and telomere maintenance; involved in transcription elongation as demonstrated /.../ G-less-based run-on (GLRO) assay; The PAF1 complex is a multifunctional complex. Involved in transcription initiation via genetic interactions with TATA- binding proteins. Involved in elongation. It regulates 3’-end formation of snR47 by modulating the recruitment or stable association of NRD1 and NAB3 with RNA polymerase II. Also has [...] (393 aa)
Copper-sensing transcription factor involved in regulation of genes required for high affinity copper transport; Regulatory protein involved in Cu/Fe utilization and stress resistance. Involved in basal level transcription of FRE1 and H(2)O(2)-induced transcription of CTT1. Regulates the transcription of CTR1 and CTR3 via the copper ion responsive elements in their promoters. Required for degradation of CTR1 (417 aa)
Ferric reductase and cupric reductase, reduces siderophore-bound iron and oxidized copper prior to uptake by transporters; expression induced by low copper and iron levels; Metalloreductase responsible for reducing extracellular iron and copper prior to import. Catalyzes the reductive uptake of Fe(3+)-salts and Fe(3+) bound to catecholate or hydroxamate siderophores. Fe(3+) is reduced to Fe(2+), which then dissociates from the siderophore and can be imported by the high-affinity Fe(2+) transport complex in the plasma membrane. Also participates in Cu(2+) reduction and Cu(+) uptake (686 aa)
Putative protein of unknown function; the authentic, non-tagged protein is detected in highly purified mitochondria in high-throughput studies (290 aa)
Multidrug transporter of the major facilitator superfamily, required for resistance to quinidine, barban, cisplatin, and bleomycin; may have a role in potassium uptake; Multidrug resistance transporter involved in resistance and adaptation to quinidine and to the herbicide barban (4-chloro- 2-butynyl [3-chlorophenyl] carbamate). Implicated in potassium uptake (542 aa)
Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data (132 aa)
