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

cki-2CKI family (Cyclin-dependent Kinase Inhibitor). (259 aa)    
Predicted Functional Partners:
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 [...]

skpt-1
F-box domain-containing protein.
   
 0.917
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).
   
 0.914
cdk-2
Cyclin-dependent kinase 2; Serine/threonine-protein kinase which, in association with cye-1, 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. Phosphorylation and inhibition of the translational repressor gld-1 by the cdk-2/cye-1 complex regulates the pool of germline stem cells and the size of the mitotic zone in the gonads by preventing entry into meiosis.
   
 0.892
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.
     
0.857
pcn-1
Proliferating cell nuclear antigen; This protein is an auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase's processibility during elongation of the leading strand; Belongs to the PCNA family.
   
 
 0.853
mpk-1
Mitogen-activated protein kinase mpk-1; Function in let-60 Ras signaling pathway; acts downstream of lin-45 raf kinase, but before the lin-1 gene product in controlling vulval cell differentiation. Plays a negative role in proximal germline proliferation in the mitotic zone. Required for progression of developing oocytes through the pachytene stage. In oocytes, inhibits the activity of the chloride channel clh-3, likely by activating gck-3. Plays a role in response to M.nematophilum-mediated bacterial infection by promoting tail swelling and preventing constipation. Involved in fluid h [...]

xpo-1
Importin N-terminal domain-containing protein.
   
 0.831
cdk-4
Cyclin-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).
   
 0.819
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 [...]
