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

Cdk2Cyclin-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. (314 aa)    
Predicted Functional Partners:
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.
 
 
 0.999
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.
   
 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.
   
 0.996
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.
   
 
 0.992
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.
   
 0.988
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.
   
 0.986
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.
   
 0.984
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.
   
 0.981
Cdc45
CDC45L (CDC45L) encodes a protein that contributes to 3'-5' DNA helicase activity of the Cdc45/Mcm2-7/GINS complex. It is involved in chromosome condensation and the regulation of the mitotic G1/S transition.
   
 0.980
dup
Double parked (dup) encodes an essential protein for the initiation of DNA replication due to its recruitment of the MCM helicase to replication origins.
   
 0.980
