STRINGSTRING
MOT1 protein (Saccharomyces cerevisiae) - STRING interaction network
"MOT1" - Essential abundant protein involved in regulation of transcription, removes Spt15p 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

MOT1Essential abundant protein involved in regulation of transcription, removes Spt15p (TBP) from DNA via its C-terminal ATPase activity, forms a complex with TBP that binds TATA DNA with high affinity but with altered specificity; Regulates transcription in association with TATA binding protein (TBP). Removes TBP from the TATA box via its C-terminal ATPase activity. Both transcription activation and repression require its ATPase activity (1867 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)

BUR6
Subunit of a heterodimeric NC2 transcription regulator complex with Ncb2p; complex binds to TBP and can repress transcription by preventing preinitiation complex assembly or stimulate activated transcription; homologous to human NC2alpha; Component of the NC2 complex which represses RNA polymerase II transcription through binding to SPT15/TBP and thereby inhibiting the assembly of the preinitiation complex. The NC2 complex may also mediate transcriptional activation from TATA- driven promoters through association with SPT15/TBP (142 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)

NCB2
Subunit of a heterodimeric NC2 transcription regulator complex with Bur6p; complex binds to TBP and can repress transcription by preventing preinitiation complex assembly or stimulate activated transcription; homologous to human NC2beta; Component of the NC2 complex which represses RNA polymerase II transcription through binding to SPT15/TBP and thereby inhibiting the assembly of the preinitiation complex. The NC2 complex may also mediate transcriptional activation from TATA- driven promoters through association with SPT15/TBP (146 aa)

HHF1
Histone H4, core histone protein required for chromatin assembly and chromosome function; one of two identical histone proteins (see also HHF2); contributes to telomeric silencing; N-terminal domain involved in maintaining genomic integrity; Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-trans [...] (103 aa)

HTB1
Histone H2B, core histone protein required for chromatin assembly and chromosome function; nearly identical to HTB2; Rad6p-Bre1p-Lge1p mediated ubiquitination regulates transcriptional activation, meiotic DSB formation and H3 methylation; Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translat [...] (131 aa)

STH1
ATPase component of the RSC chromatin remodeling complex; required for expression of early meiotic genes; essential helicase-related protein homologous to Snf2p; Catalytic component of the chromatin structure- remodeling complex (RSC), which is involved in transcription regulation and nucleosome positioning. RSC is responsible for the transfer of a histone octamer from a nucleosome core particle to naked DNA. The reaction requires ATP and involves an activated RSC-nucleosome intermediate. Remodeling reaction also involves DNA translocation, DNA twist and conformational change. As a rec [...] (1359 aa)

ISW2
ATP-dependent DNA translocase involved in chromatin remodeling; ATPase component that, with Itc1p, forms a complex required for repression of a-specific genes, INO1, and early meiotic genes during mitotic growth; Catalytic component of the ISW2 complex, which acts in remodeling the chromatin by catalyzing an ATP-dependent alteration in the structure of nucleosomal DNA. THe ISW2 complex is involved in coordinating transcriptional repression and in inheritance of telomeric silencing. It is involved in repression of MAT a- specific genes, INO1, and early meiotic genes during mitotic growt [...] (1120 aa)

HTA2
Histone H2A, core histone protein required for chromatin assembly and chromosome function; one of two nearly identical (see also HTA1) subtypes; DNA damage-dependent phosphorylation by Mec1p facilitates DNA repair; acetylated by Nat4p; Core component of nucleosome which plays a central role in DNA double strand break (DSB) repair. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template.
