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

Cdk1Cyclin-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. (297 aa)    
Predicted Functional Partners:
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.

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
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.
   
 
 0.998
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.
   
 0.997
CycB3
G2/mitotic-specific cyclin-B3; Cyclins are positive regulatory subunits of the cyclin- dependent kinases (CDKs), and thereby play an essential role in the control of the cell cycle, notably via their destruction during cell division. Probably functions redundantly with other cyclins in regulation of cell cycle. Its presence may be required to delay a deadline for completing cytokinesis that is ordinary imposed by nuclear envelope reformation. Degradation of CycB and CycB3 promote cytokinesis furrow initiation and ingression. Required with CycB for female fertility.
   
 
 0.990
fzy
FI02843p; Fizzy (fzy) encodes WD40 domain protein required for the full ubiquitin ligase activity of the anaphase-promoting complex/cyclosome (APC/C) in mitosis and meiosis. The product of fzy functions to target substrates for destruction and drive metaphase and anaphase transition.
   
 0.987
Cks85A
Cyclin-dependent kinase subunit 85A (Cks85A) encodes a small protein that interacts with the products of Cdk1 and Cdk2. It also functions with the product of Skp2 to target specific substrates for destruction, including the product of dap. It is required for larval growth and to maintain diploidy in imaginal tissues.
   
 
 0.982
Bub3
Bub3, isoform A; Bub3 (Bub3) encodes a protein that functions in the spindle assembly checkpoint (SAC) pathway. This mitotic checkpoint pathway inhibits the APC/C complex and hence the transition from metaphase to anaphase, as long as there are free kinetochores that are not yet attached to the mitotic spindle in the cell. The product of Bub3 is localized at the kinetochore during mitosis with maximal levels observed at free kinetochores. Together with other SAC proteins it forms mitotic checkpoint complexes that bind and inhibit the APC/C.
   
 0.982
fzr
Fizzy-related, isoform A; Fizzy-related (fzr) encodes a protein that binds to the Anaphase-Promoting Complex/Cyclosome (APC/C) ubiquitin ligase to stimulate its activity during G1 phase.
   
 0.981
BubR1
Bub1-related kinase (BubR1) encodes a motif-rich protein with a C-terminal serine-threonine kinase domain. During prometaphase and metaphase, it plays important roles in spindle assembly checkpoint signalling, stabilization of kinetochore-microtuble attachments and chromosome alignment. It is also essential to maintain sister-chromatid cohesion during meiotic progression and for normal maintenance of Synaptonemal Complex in females.
