STRINGSTRING
TIR1 protein (Saccharomyces cerevisiae) - STRING interaction network
"TIR1" - Cell wall mannoprotein of the Srp1p/Tip1p family of serine-alanine-rich 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

TIR1Cell wall mannoprotein of the Srp1p/Tip1p family of serine-alanine-rich proteins; expression is downregulated at acidic pH and induced by cold shock and anaerobiosis; abundance is increased in cells cultured without shaking; Component of the cell wall. Required for anaerobic growth (254 aa)    
Predicted Functional Partners:
DAN1
Cell wall mannoprotein with similarity to Tir1p, Tir2p, Tir3p, and Tir4p; expressed under anaerobic conditions, completely repressed during aerobic growth; Component of the cell wall (298 aa)

SRP1
Karyopherin alpha homolog, forms a dimer with karyopherin beta Kap95p to mediate import of nuclear proteins, binds the nuclear localization signal of the substrate during import; may also play a role in regulation of protein degradation; Binds specifically and directly to substrates containing either a simple or bipartite NLS motif. Promotes docking of import substrates to the nuclear envelope. Seems to act as a cytosolic receptor for both simple and bipartite NLS motifs (By similarity) (542 aa)

ANB1
Translation elongation factor eIF-5A, previously thought to function in translation initiation; similar to and functionally redundant with Hyp2p; undergoes an essential hypusination modification; expressed under anaerobic conditions; mRNA-binding protein involved in translation elongation. Has an important function at the level of mRNA turnover, probably acting downstream of decapping. Involved in actin dynamics and cell cycle progression, mRNA decay and probably in a pathway involved in stress response and maintenance of cell wall integrity. Essential for polarized growth, a process n [...] (157 aa)

KAP95
Karyopherin beta, forms a complex with Srp1p/Kap60p; interacts with nucleoporins to mediate nuclear import of NLS-containing cargo proteins via the nuclear pore complex; regulates PC biosynthesis; GDP-to-GTP exchange factor for Gsp1p; Importin beta subunit that functions in nuclear protein import through association with the importin alpha subunit, which binds to the classical nuclear localization signal (cNLS) in cargo substrates (PubMed-7622450). Docking of the importin/substrate complex to the nuclear pore complex (NPC) is mediated by importin beta through binding to nucleoporin FxF [...] (861 aa)

STM1
Protein required for optimal translation under nutrient stress; perturbs association of Yef3p with ribosomes; involved in TOR signaling; binds G4 quadruplex and purine motif triplex nucleic acid; helps maintain telomere structure; Binds specifically G4 quadruplex (these are four- stranded right-handed helices, stabilized by guanine base quartets) and purine motif triplex (characterized by a third, antiparallel purine-rich DNA strand located within the major groove of a homopurine stretch of duplex DNA) nucleic acid structures. These structures may be present at telomeres or in rRNAs. A [...] (273 aa)

THO2
Subunit of the THO complex; THO is required for efficient transcription elongation and involved in transcriptional elongation-associated recombination; required for LacZ RNA expression from certain plasmids; Component the THO subcomplex of the TREX complex, which operates in coupling transcription elongation to mRNA export. The THO complex is recruited to transcribed genes and moves along the gene with the elongating polymerase during transcription. THO is important for stabilizing nascent RNA in the RNA polymerase II elongation complex by preventing formation of DNA-RNA hybrids behind [...] (1597 aa)

SRB5
Subunit of the RNA polymerase II mediator complex; associates with core polymerase subunits to form the RNA polymerase II holoenzyme; essential for transcriptional regulation; required for proper termination of transcription for some genes; involved /.../lomere maintenance; Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. The Mediator complex, having a [...] (307 aa)

NOP7
Component of several different pre-ribosomal particles; forms a complex with Ytm1p and Erb1p that is required for maturation of the large ribosomal subunit; required for exit from G<sub>0</sub> and the initiation of cell proliferation; Component of the NOP7 complex, which is required for maturation of the 25S and 5.8S ribosomal RNAs and formation of the 60S ribosome (605 aa)

STO1
Large subunit of the nuclear mRNA cap-binding protein complex, interacts with Npl3p to carry nuclear poly(A)+ mRNA to cytoplasm; also involved in nuclear mRNA degradation and telomere maintenance; orthologous to mammalian CBP80; Component of the CBC complex, which binds co- transcriptionally to the 5’-cap of pre-mRNAs and is involved in maturation, export and degradation of nuclear mRNAs. The CBC complex is required for efficient pre-mRNA splicing through efficient commitment complex and spliceosome formation. Together with NPL3, the CBC complex is required for export of mRNAs out of t [...] (861 aa)
