STRINGSTRING
MDR1 protein (Saccharomyces cerevisiae) - STRING interaction network
"MDR1" - Cytoplasmic GTPase-activating protein for Ypt/Rab transport GTPases Ypt6p, Ypt31p and Sec4p 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

MDR1Cytoplasmic GTPase-activating protein for Ypt/Rab transport GTPases Ypt6p, Ypt31p and Sec4p; involved in recycling of internalized proteins and regulation of Golgi secretory function; Stimulates specifically the GTPase activity of SEC4, YPT6 and YPT36. Inactivates YPT6 during recycling between the endosome and the Golgi compartments (950 aa)    
Predicted Functional Partners:
STE6
Plasma membrane ATP-binding cassette (ABC) transporter required for the export of a-factor, catalyzes ATP hydrolysis coupled to a-factor transport; contains 12 transmembrane domains and two ATP binding domains; expressed only in MATa cells; STE6 is required in yeast MATA cells for production of A-factor pheromone. STE6 is involved in the transport of the farnesyl-derivation of the A-factor pheromone (1290 aa)
           
  0.913
ERG11
Lanosterol 14-alpha-demethylase; catalyzes the C-14 demethylation of lanosterol to form 4,4’’-dimethyl cholesta-8,14,24-triene-3-beta-ol in the ergosterol biosynthesis pathway; member of the cytochrome P450 family; associated and coordinately regula /.../th the P450 reductase Ncp1p; Catalyzes C14-demethylation of lanosterol which is critical for ergosterol biosynthesis. It transforms lanosterol into 4,4’-dimethyl cholesta-8,14,24-triene-3-beta-ol (530 aa)
           
  0.872
UTP7
Nucleolar protein, component of the small subunit (SSU) processome containing the U3 snoRNA that is involved in processing of pre-18S rRNA; Involved in nucleolar processing of pre-18S ribosomal RNA (554 aa)
       
      0.868
YPT6
Rab family GTPase, Ras-like GTP binding protein involved in the secretory pathway, required for fusion of endosome-derived vesicles with the late Golgi, maturation of the vacuolar carboxypeptidase Y; has similarity to the human GTPase, Rab6; Protein transport. Might participate in post-Golgi transport (215 aa)
     
 
  0.799
SEC4
Rab family GTPase essential for vesicle-mediated exocytic secretion and autophagy; associates with the exocyst component Sec15p and may regulate polarized delivery of transport vesicles to the exocyst at the plasma membrane; Involved in exocytosis. Maybe by regulating the binding and fusion of secretory vesicles with the cell surface. The GTP- bound form of SEC4 may interact with an effector, thereby stimulating its activity and leading to exocytotic fusion. SEC4 may be an upstream activator of the 19.5S SEC8/SEC15 particle. SEC4 probably interacts directly with SEC8; it could serve as [...] (215 aa)

PDR5
Plasma membrane ATP-binding cassette (ABC) transporter, multidrug transporter actively regulated by Pdr1p; also involved in steroid transport, cation resistance, and cellular detoxification during exponential growth; Active efflux of weakly charged organic compounds of 90 cubic Angstroms to 300 cubic Angstroms surface volume. Confers resistance to numerous chemicals including cycloheximide, sulfomethuron methyl, steroids, antiseptics, antibiotics, anticancer, herbicides, mycotoxins, insecticides, ionophores, alkaloids, flavonoids, phenothiazines, organotin compounds, carbazoles, lysoso [...] (1511 aa)
           
  0.757
QDR1
Multidrug transporter of the major facilitator superfamily, required for resistance to quinidine, ketoconazole, fluconazole, and barban; Multidrug resistance transporter involved in resistance and adaptation to quinidine and ketoconazole (563 aa)
       
 
  0.751
PDR3
Transcriptional activator of the pleiotropic drug resistance network, regulates expression of ATP-binding cassette (ABC) transporters through binding to cis-acting sites known as PDREs (PDR responsive elements); post-translationally up-regulated in /.../lacking a functional mitochondrial genome; PDR1 and PDR3 jointly control the transcription level of both SNQ2 and PDR5 (976 aa)
           
  0.747
PDR1
Zinc cluster protein that is a master regulator involved in recruiting other zinc cluster proteins to pleiotropic drug response elements (PDREs) to fine tune the regulation of multidrug resistance genes; Positive regulator of proteins involved in permeability. PDR1 and PDR3 jointly control the transcription level of both SNQ2 and PDR5 (1068 aa)
           
  0.743
SNQ2
Plasma membrane ATP-binding cassette (ABC) transporter, multidrug transporter involved in multidrug resistance and resistance to singlet oxygen species; Could be an ATP-dependent permease. Confers hyper- resistance to the mutagens 4-nitroquinoline-N-oxide (4-NQO) and triaziquone, as well as to the chemicals sulphomethuron methyl phenanthroline when present in multiple copies. Exhibits nucleoside triphosphatase activity (1501 aa)
