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

CycBG2/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. (530 aa)    
Predicted Functional Partners:
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.

polo
Serine/threonine-protein kinase polo; May play a role in regulating both nuclear and cytoplasmic aspects of the mitotic cycle. Regulates localization of the augmin complex during mitosis by ensuring its location on mitotic spindles. Also regulates augmin complex localization during male meiosis by promoting its placement at kinetochores while preventing its association with spindle microtubules ; Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. CDC5/Polo subfamily.

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.
   
 0.993
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
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.
  
 
0.984
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.
   
 0.977
stg
M-phase inducer phosphatase; This protein functions as a dosage-dependent inducer in mitotic control. It is a tyrosine protein phosphatase required for progression of the cell cycle. It may directly dephosphorylate Cdk1 and activate the Cdk1 activity.
   
 0.971
Myt1
Membrane-associated tyrosine- and threonine-specific cdc2-inhibitory kinase; Acts as a negative regulator of entry into mitosis (G2 to M transition) by phosphorylation of Cdk1 specifically when Cdk1 is complexed to cyclins. Mediates phosphorylation of Cdk1 predominantly on 'Thr-14'. Also involved in Golgi fragmentation. May be involved in phosphorylation of Cdk1 on 'Tyr- 15' to a lesser degree, however tyrosine kinase activity is unclear and may be indirect. May be a downstream target of Notch signaling pathway during eye development. Belongs to the protein kinase superfamily. Ser/Thr [...]

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.
