STRINGSTRING
HMO1 protein (Saccharomyces cerevisiae) - STRING interaction network
"HMO1" - Chromatin associated high mobility group 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

HMO1Chromatin associated high mobility group (HMG) family member involved in genome maintenance; rDNA-binding component of the Pol I transcription system; associates with a 5’-3’ DNA helicase and Fpr1p, a prolyl isomerase; DNA-binding protein that is probably part of the rDNA transcription apparatus. Acts synergetically with the RPA49 subunit of RNA polymerase I during rDNA transcription. May participate in mutagenesis control (246 aa)    
Predicted Functional Partners:
SPT15
TATA-binding protein, general transcription factor that interacts with other factors to form the preinitiation complex at promoters, essential for viability; General transcription factor that functions at the core of the DNA-binding general transcription factor complex TFIID. Binding of TFIID to a promoter (with or without TATA element) is the initial step in preinitiation complex (PIC) formation. TFIID plays a key role in the regulation of gene expression by RNA polymerase II through different activities such as transcription activator interaction, core promoter recognition and select [...] (240 aa)

SPT16
Subunit of the heterodimeric FACT complex (Spt16p-Pob3p), which associates with chromatin via interaction with Nhp6Ap and Nhp6Bp, and reorganizes nucleosomes to facilitate access to DNA by RNA and DNA polymerases; Component of the FACT complex, a general chromatin factor that acts to reorganize nucleosomes. The FACT complex is involved in multiple processes that require DNA as a template such as mRNA elongation, DNA replication and DNA repair. During transcription elongation the FACT complex acts as a histone chaperone that both destabilizes and restores nucleosomal structure. It facil [...] (1035 aa)

SUA7
Transcription factor TFIIB, a general transcription factor required for transcription initiation and start site selection by RNA polymerase II; General factor that plays a major role in the activation of eukaryotic genes transcribed by RNA polymerase II (345 aa)
     
  0.835
RPA49
RNA polymerase I subunit A49; DNA-dependent RNA polymerases catalyze the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase I (Pol I) which synthesizes ribosomal RNA precursors. Besides, RNA polymerase I has intrinsic RNA cleavage activity. The heterodimer formed by RPA34 and RPA49 stimulates transcript elongation by Pol I. Subunit RPA49 can bind both single-stranded and double-stranded DNA (415 aa)
       
 
  0.823
HSM3
Proteasome-interacting protein involved in the assembly of the base subcomplex of the 19S proteasomal regulatory particle (RP); involved in DNA mismatch repair during slow growth; weak similarity to Msh1p; related to human 19S subunit S5b; Involved in DNA mismatch repair in slow-growing cells. Acts as a chaperone during the assembly of the 26S proteasome, specifically of the base subcomplex of the 19S regulatory complex (RC) (480 aa)
       
 
  0.791
TAF11
TFIID subunit (40 kDa), involved in RNA polymerase II transcription initiation, similar to histone H3 with atypical histone fold motif of Spt3-like transcription factors; Functions as a component of the DNA-binding general transcription factor complex TFIID. Binding of TFIID to a promoter (with or without TATA element) is the initial step in pre- initiation complex (PIC) formation. TFIID plays a key role in the regulation of gene expression by RNA polymerase II through different activities such as transcription activator interaction, core promoter recognition and selectivity, TFIIA and [...] (346 aa)

RPL20A
Protein component of the large (60S) ribosomal subunit, nearly identical to Rpl20Bp and has similarity to rat L18a ribosomal protein (172 aa)
     
      0.787
RPL17B
Protein component of the large (60S) ribosomal subunit, nearly identical to Rpl17Ap and has similarity to E. coli L22 and rat L17 ribosomal proteins (184 aa)
     
 
  0.784
IFH1
Coactivator that regulates transcription of ribosomal protein (RP) genes; recruited to RP gene promoters during optimal growth conditions via Fhl1p; subunit of CURI, a complex that coordinates RP production and pre-rRNA processing; Controls the pre-rRNA processing machinery in conjunction with FHL1. Could convert FHL1 from a repressor to an activator (1085 aa)
       
 
  0.782
RAP1
DNA-binding protein involved in either activation or repression of transcription, depending on binding site context; also binds telomere sequences and plays a role in telomeric position effect (silencing) and telomere structure; Essential regulatory protein in yeast whose DNA-binding sites are found at three types of chromosomal elements- promoters, silencers, and telomeres. RAP1 is also involved in the regulation of telomere structure, where its binding sites are found within the terminal poly[C(1-3)A] sequences. The opposite regulatory functions of RAP1 are not intrinsic to its bindi [...] (827 aa)
