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

CycDCyclin 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. (477 aa)    
Predicted Functional Partners:
Cdk4
Cyclin-dependent kinase 4 (Cdk4) encodes a protein that contributes to cell cycle progression and cell growth. It is involved in the regulation of JAK-STAT and TORC1 signalling pathways.
   
 0.999
dap
RE12958p; Dacapo (dap) encodes a Cyclin-dependent kinase inhibitor in the CIP/KIP family. It binds to CycE-Cdk2 complexes and thereby inhibits their protein kinase activity. Upregulation of dap is required after the last mitosis for arresting cells in G1/G0 before terminal differentiation in many post-mitotic cell types.
   
 0.995
Cdk2
Cyclin-dependent kinase 2 (Cdk2) encodes a catalytic protein kinase subunit that can only become active after association with the product of CycE. The protein kinase activity of the CycE-Cdk2 complex controls important aspects of progression through the G1 and S phases of the cell cycle. In addition, periodic CycE-Cdk2 activity regulates progression through endoreduplication cycles; Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily.
   
 
 0.992
Rbf
Retinoblastoma-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.
   
 0.983
Cdk1
Cyclin-dependent kinase 1 (Cdk1) encodes a catalytic protein kinase subunit that can only become active after association with either CycA, CycB or CycB3 products. The protein kinase activities of these complexes (CycA-Cdk1, CycB-Cdk1, CycB3-Cdk1) control important aspects of progression through the cell cycle. Functionally, the different Cdk1 complexes are partially redundant. They phosphorylate hundreds of target proteins and are most important for progression into and through mitotic and meiotic M phases.
   
 
 0.967
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.
   
 0.963
Rbf2
Retinoblastoma protein homolog RBF2; It is involved in the biological process described with: cell differentiation; regulation of mitotic cell cycle; negative regulation of G1/S transition of mitotic cell cycle; negative regulation of transcription by RNA polymerase II.
   
 0.960
Cdk5
Cyclin-dependent kinase 5 (Cdk5) encodes a protein serine-threonine kinase of the cyclin-dependent kinase family whose activity is largely restricted to post-mitotic neurons. It is required for synaptic homeostasis and fidelity of axon patterning, and altered activity causes adult-onset neurodegeneration.
   
 
 0.877
Skp2
S-phase kinase-associated protein 2 (Skp2) encodes the substrate recognizing component of the SCF-Skp2 ubiquitin ligase. It functions with the product of Cks85A to target the product of dap for destruction. It is required for larval growth and to maintain diploidy in imaginal tissues.
   
 0.871
HDAC4
Histone deacetylase 4, isoform G; Histone deacetylase 4 (HDAC4) encodes a Class IIa histone deacetylase that modulates gene expression by associating with transcriptional factors. It is regulated by nucleocytoplasmic shuttling and contributes to embryogenesis, muscle development, circadian function, energy balance and memory.
