STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

RbfRetinoblastoma-family protein (Rbf) encodes a protein that binds to members of the E2F transcription factors and forms the DREAM complex, which regulates genes with diverse biological functions including cell cycle regulators, apoptosis regulators, and DNA replication/repair factors. The product of Rbf can also bind chromosomal proteins and modulate genome stability. It is negatively regulated by CycE-Cdk2 and CycD-Cdk4 cyclin-dependent kinase complexes. (845 aa)    
Predicted Functional Partners:
E2f1
Transcription factor E2f1; Transcriptional activator that binds to E2f sites. Required for wild-type growth in mitotic and polytene tissues, Contributes to the expression of replication genes at the G1-S transition and Cyclin E. Activates cell proliferation in wing imaginal disk, which requires expression of vg; Belongs to the E2F/DP family.
   
 0.999
E2f2
Transcription factor E2F2; Transcriptional repressor that binds to E2f sites and represses E2f-regulated target genes. Binding to E2f sites requires transcription factor Dp. Acts synergistically with Rbf2 to antagonize E2f1-mediated transcriptional activation. Component of the DREAM complex, a multiprotein complex that can both act as a transcription activator or repressor depending on the context. The DREAM complex is required for recruiting E2f2 at differentiation-specific promoters and for stabilizing E2f2-Rbf complexes during S phase. During development, the complex represses trans [...]

lin-52
Lin-52 (lin-52) encodes a subunit of the MuvB core complex. The MuvB core binds to the oncoprotein encoded by Myb and the Rbf-E2f2-Dp tumor suppressor complex, thereby controlling the expression of many genes, including critical regulators of the cell cycle.
    
 0.998
Dp
Transcription factor Dp; Component of the DREAM complex, a multiprotein complex that can both act as a transcription activator or repressor depending on the context. In follicle cells, the complex plays a central role in the site-specific DNA replication at the chorion loci. During development, the complex represses transcription of developmentally controlled E2F target genes. Can stimulate E2F-dependent transcription.
   
 0.997
Caf1-55
Probable histone-binding protein Caf1; Core histone-binding subunit that may target chromatin assembly factors, chromatin remodeling factors and histone deacetylases to their histone substrates in a manner that is regulated by nucleosomal DNA. Component of several complexes which regulate chromatin metabolism. These include the chromatin assembly factor 1 (CAF-1) complex, which is required for chromatin assembly following DNA replication and DNA repair; the nucleosome remodeling and deacetylase complex (the NuRD complex), which promotes transcriptional repression by histone deacetylati [...]

mip130
Myb-interacting protein 130 (mip130) encodes a subunit of the MuvB core complex. The MuvB core binds to the oncoprotein encoded by Myb and the Rbf-E2f2-Dp tumor suppressor complex, thereby controlling the expression of many genes, including critical regulators of the cell cycle.
   
 0.992
mip40
Myb-interacting protein 40 (mip40) encodes a subunit of the MuvB core complex. The MuvB core binds to the oncoprotein encoded by Myb and the Rbf-E2f2-Dp tumor suppressor complex, thereby controlling the expression of many genes, including critical regulators of the cell cycle.
    
 0.988
mip120
Protein lin-54 homolog; Component of the DREAM complex, a multiprotein complex that can both act as a transcription activator or repressor depending on the context. In follicle cells, the complex plays a central role in the site-specific DNA replication at the chorion loci. During development, the complex represses transcription of developmentally controlled E2F target genes.
   
 0.987
CycD
Cyclin D (CycD) encodes a protein that binds to the product of Cdk4, thereby promoting its kinase activity. The CycD-Cdk4 complex promotes cell growth and progression through the G1 phase - it phosphorylates and thereby inhibits the product of Rbf, the ortholog of the human tumor suppressor retinoblastoma protein.
   
 0.983
CycE
G1/S-specific cyclin-E; Essential for the control of the cell cycle at the G1/S (start) transition. Targeted by archipelago for degradation by the SFC ubiquitin ligase complex.
