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

cdk-4Cyclin-dependent kinase 4 homolog; Serine/threonine-protein kinase which, in association with cyclin D-like protein cyd-1, is required for the progression through the G1 phase of the cell cycle during postembryonic development by phosphorylating and inhibiting lin-35 and fzr-1. In complex with cyd-1, involved in sex determination during gonadogenesis by regulating the asymmetric division of the somatic gonadal precursor cell (SGP). (406 aa)    
Predicted Functional Partners:
cyd-1
G1/S-specific cyclin-D; In association with cdk-4, regulates the progression through the G1 phase of the cell cycle during postembryonic development. Regulates proliferation of the coelomocyte lineage and intestinal cells during late embryogenesis. In complex with cdk-4, involved in sex determination during gonadogenesis by regulating the asymmetric division of the somatic gonadal precursor cell (SGP).

cya-1
G2/mitotic-specific cyclin-A1; Involved in the control of the cell cycle after S phase. May bind to and activate cdk-1 and/or cdk-2 to promote cell cycle progression. Necessary for embryogenesis. Belongs to the cyclin family. Cyclin AB subfamily.
   
 
 0.983
lin-35
Retinoblastoma-like protein homolog lin-35; Key regulator of cell division which acts as a transcriptional repressor and negatively regulates cell cycle progression in its active unphosphorylated form, but allows cell cycle progression when phosphorylated. When unphosphorylated and in its active form, interacts with E2F transcription factors such as efl-1 to repress their transcriptional activity and negatively regulate the progression through the G1 phase of the cell cycle during postembryonic development. May furthermore act with cell cycle regulator cki-1 to negatively regulate cell [...]

cye-1
G1/S-specific cyclin-E; Essential for the control of the cell cycle at the G1/S (start) transition. In association with cdk-2, regulates proliferation, quiescent state and cell fate during the development of several cell lineages. In the embryo, initiates the establishment of cell polarity through the recruitment of the centrosomal proteins spd-2 and spd-5 during prophase. During the development of the vulva, controls the onset of vulval cell terminal differentiation by controlling the duration of G1 phase. During hypoderm development at early larval stages, controls syncytial fate of [...]

cya-2
CYCLIN domain-containing protein; Belongs to the cyclin family.
   
 
 0.973
cyb-2.2
Cyclin N-terminal domain-containing protein; Belongs to the cyclin family.
   
 
 0.959
cyb-2.1
Cyclin N-terminal domain-containing protein; Belongs to the cyclin family.
   
 
 0.959
cdc-6
Cell division control protein; Involved in the initiation of DNA replication. Also participates in checkpoint controls that ensure DNA replication is completed before mitosis is initiated; Belongs to the CDC6/cdc18 family.
   
 
 0.924
fzr-1
WD_REPEATS_REGION domain-containing protein.
   
 
 0.918
cki-1
Cyclin-dependent kinase inhibitor 1; Negative cell-cycle regulator that functions at the G1-to-S- phase transition. Required for suspension of the cell cycle in dauer larvae and starved L1 larvae. In vulval precursor cells (VPCs), a pathway of heterochronic genes acts via cki-1 to maintain VPCs in G1 during the L2 larval stage. Cul-2 may function in ubiquitin-mediated degradation by targeting cki-1 for degradation. Involved in distal tip cell development by repressing and modulating cye-1/cdk-2 activity levels in Z1.aa/Z4.pp and in Z1.ap/Z4.pa. Belongs to the CDI family.
