STRINGSTRING
CSR2 protein (Saccharomyces cerevisiae) - STRING interaction network
"CSR2" - Nuclear protein proposed to regulate utilization of nonfermentable carbon sources and endocytosis of plasma membrane proteins 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

CSR2Nuclear protein proposed to regulate utilization of nonfermentable carbon sources and endocytosis of plasma membrane proteins; overproduction suppresses chs5 spa2 lethality at high temp; ubiquitinated by Rsp5p, deubiquitinated by Ubp2p; Transcription factor involved in the regulation of fermentation and aerobic oxidation. Acts as a repressor of CYC1, which is involved in electron flow through the mitochondria under aerobic condition. Required for pseudohyphal formation upon nitrogen starvation. May be involved in viability at stationary phase and aging (1121 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)

TOM1
E3 ubiquitin ligase of the hect-domain class; has a role in mRNA export from the nucleus and may regulate transcriptional coactivators; involved in degradation of excess histones; Probable ubiquitin ligase protein involved in many cellular processes, such as transcription regulation, maintenance of nuclear structure, cell cycle, mRNA export and rRNA maturation. E3 ubiquitin ligase proteins mediate ubiquitination and subsequent proteasomal degradation of target proteins. Involved in transcription regulation by interacting, and probably mediating, ubiquitination of some subunit of the SA [...] (3268 aa)

HUL4
Protein with similarity to hect domain E3 ubiquitin-protein ligases, not essential for viability; Probable E3 ubiquitin-protein ligase, component of the TRAMP (TRF4) complex which has a poly(A) RNA polymerase activity and is involved in a post-transcriptional quality control mechanism limiting inappropriate expression of genetic information. Polyadenylation is required for the degradative activity of the exosome on several of its nuclear RNA substrates (892 aa)

HUL5
Multiubiquitin chain assembly factor (E4); proteasome processivity factor that elongates polyUb chains on substrates, opposing Ubp6p, a branched polyubiquitin protease; required for retrograde transport of misfolded proteins during ERAD; Probable 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. Non essential (910 aa)

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)

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.
