STRINGSTRING
BUL1 protein (Saccharomyces cerevisiae) - STRING interaction network
"BUL1" - Ubiquitin-binding component of the Rsp5p E3-ubiquitin ligase complex, functional homolog of Bul2p, disruption causes temperature-sensitive growth, overexpression causes missorting of amino acid permeases 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

BUL1Ubiquitin-binding component of the Rsp5p E3-ubiquitin ligase complex, functional homolog of Bul2p, disruption causes temperature-sensitive growth, overexpression causes missorting of amino acid permeases; Component of a RSP5 ubiquitin ligase complex which specifies polyubiquitination and intracellular trafficking of the general amino acid permease GAP1 as well as other permeases such as PMA1. The RSP5-BUL1/2 complex is also necessary for the heat- shock element (HSE)-mediated gene expression, nitrogen starvation GLN3-dependent transcription and pressure-induced differential regulation [...] (976 aa)    
Predicted Functional Partners:
RSP5
E3 ubiquitin ligase of the NEDD4 family; involved in regulating many cellular processes including MVB sorting, heat shock response, transcription, endocytosis, and ribosome stability; human homolog is involved in Liddle syndrome; mutant tolerates an /.../dy; ubiquitylates Sec23p; E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Component of a RSP5 ubiquitin ligase complex which specifies polyubiquitination and intracellular trafficking of the general a [...] (809 aa)
       
 
  0.980
GAP1
General amino acid permease; Gap1p senses the presence of amino acid substrates to regulate localization to the plasma membrane when needed; Permease for various amino acids as well as for GABA. Can also transport L-cysteine and beta-alanine (602 aa)
       
 
  0.905
UBI4
Ubiquitin, becomes conjugated to proteins, marking them for selective degradation via the ubiquitin-26S proteasome system; essential for the cellular stress response; encoded as a polyubiquitin precursor comprised of 5 head-to-tail repeats; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiqui [...] (381 aa)
       
 
  0.888
MCK1
Protein serine/threonine/tyrosine (dual-specificity) kinase involved in control of chromosome segregation and in regulating entry into meiosis; related to mammalian glycogen synthase kinases of the GSK-3 family; May be an autophosphorylating tyrosine kinase, a bifunctional (serine/tyrosine-specific) protein kinase, or a serine kinase that is a substrate for an associated tyrosine kinase. MCK1 is a transcriptional activator of IME1, it stimulates spore maturation, and play a positive regulatory role in both mitotic centromere function and activation of early meiotic gene expression (375 aa)
       
 
  0.871
TAT2
High affinity tryptophan and tyrosine permease, overexpression confers FK506 and FTY720 resistance; Required for high-affinity tryptophan transport. Also transports cysteine, phenyalanine and tyrosine (592 aa)
       
 
  0.856
UBP2
Ubiquitin-specific protease that removes ubiquitin from ubiquitinated proteins; interacts with Rsp5p and is required for MVB sorting of membrane proteins; can cleave polyubiquitin and has isopeptidase activity; Has an ATP-independent isopeptidase activity, cleaving at the C-terminus of the ubiquitin moiety in natural or engineered linear fusion proteins, irrespective of their size or the presence of an N-terminal extension to ubiquitin. Removes ubiquitin chains that initiate proteolysis of FZO1 and inhibit mitochondrial fusion (1272 aa)
       
 
  0.836
LDB19
Protein involved in regulating the endocytosis of plasma membrane proteins by recruiting the ubiquitin ligase Rsp5p to its target; localization changes in response to nutrient levels; null mutant has reduced affinity for alcian blue dye; May be involved in protein-linked oligosaccharide phosphorylation since the deletion reduces the negative charge of the cell surface. Involved in the resistance to EDTA, cadmium chloride, cycloheximide, 6-dimethylaminopurine, methyl caffeate, beta-chloro-L-alanine, caffeine and cerulenin (818 aa)
     
 
  0.834
GLN3
Transcriptional activator of genes regulated by nitrogen catabolite repression (NCR), localization and activity regulated by quality of nitrogen source; Positive nitrogen regulatory protein. Required for the activation of transcription of a number of genes (including the allantoin pathway genes) in response to the replacement of glutamine by glutamate as source of nitrogen. Binds the nitrogen upstream activation sequence of GLN1, the gene encoding glutamine synthetase. URE2 may catalytically inactivate GLN3 in response to an increase in the intracellular concentration of glutamine (730 aa)
           
  0.829
GGA1
Golgi-localized protein with homology to gamma-adaptin, interacts with and regulates Arf1p and Arf2p in a GTP-dependent manner in order to facilitate traffic through the late Golgi; May play a role in the regulation of membrane traffic through the trans-Golgi network (557 aa)
           
  0.829
RPL40B
Fusion protein, identical to Rpl40Ap, that is cleaved to yield ubiquitin and a ribosomal protein of the large (60S) ribosomal subunit with similarity to rat L40; ubiquitin may facilitate assembly of the ribosomal protein into ribosomes; Ubiquitin- exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin [...] (128 aa)
