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

Cdk4Cyclin-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. (317 aa)    
Predicted Functional Partners:
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.
   
 0.999
CycA
G2/mitotic-specific cyclin-A; Cyclin A (CycA) encodes a protein that binds to the product of Cdk1, thereby promoting Cdk1's protein kinase activity. The CycA-Cdk1 complex controls important aspects of progression through the cell cycle, including entry into mitosis. During the G2 phase, this complex is important for prevention of premature DNA re-replication. During mitosis and G1, the product of CycA is rapidly degraded (involving APC/C and the proteasome), resulting in inactivation of Cdk1 protein kinase activity.
   
 
 0.993
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.
   
 0.974
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.
   
 0.969
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.
   
 0.954
Cdc6
Cell division control protein; Cdc6 (Cdc6) encodes an essential component of the pre-Replication complex (preRC) together with the origin recognition complex, the product of dup and MCM2-7 proteins. The preRC is present at all chromosomal origins of replication and is required for the initiation of DNA replication. The product of Cdc6 also functions in the co-ordination of DNA replication with mitosis, and may contribute to apoptosis and transcription; Belongs to the CDC6/cdc18 family.
   
 
 0.949
Cdc37
Hsp90 co-chaperone Cdc37; Co-chaperone that binds to numerous kinases and promotes their interaction with the Hsp90 complex, resulting in stabilization and promotion of their activity. Required for cytokinesis and chromosome segregation in mitosis and male meiosis. Belongs to the CDC37 family.
    
 
 0.947
Cks30A
Cyclin-dependent kinase subunit 30A (Cks30A) encodes a protein that promotes progression through female meiosis and the mitotic divisions of the early embryo. It interacts with the product of Cdk1 and is required in prometaphase for spindle assembly, and at the metaphase to anaphase transition for the destruction of the cyclin encoded by CycA.
   
 0.943
CycB
G2/mitotic-specific cyclin-B; Cyclin B (CycB) encodes a protein that binds to Cdk1, thereby promoting Cdk1's protein kinase activity. The complex CycB-Cdk1 complex induces the start of mitosis. During late metaphase of mitosis and continuing in G1, the product of CycB is rapidly degraded (involving APC/C and the proteasome), resulting in inactivation of Cdk1 protein kinase activity, and allowing termination of mitosis.
   
 
 0.936
Wee1
Wee1-like protein kinase; Wee1 kinase (Wee1) encodes a tyrosine kinase required for triggering entry into mitosis. The activity of the Wee1 product contributes to spindle assembly and alignment and separation of the chromosomes; Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. WEE1 subfamily.
