STRINGSTRING
DBF2 protein (Saccharomyces cerevisiae) - STRING interaction network
"DBF2" - Ser/Thr kinase involved in transcription and stress response in Saccharomyces cerevisiae
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

DBF2Ser/Thr kinase involved in transcription and stress response; functions as part of a network of genes in exit from mitosis; localization is cell cycle regulated; activated by Cdc15p during the exit from mitosis; Ser/Thr-protein kinase involved in the mitotic exit network (MEN) and required after the metaphase to anaphase cell cycle transition. Phosphorylates CHS2 to regulate its dynamics and chitin synthesis at the division site during cytokinesis. Coordinates septin and actomyosin ring (AMR) functions during cytokinesis through the phosphorykation of HOF1. In complex with MOB1, phosph [...] (572 aa)    
Predicted Functional Partners:
MOB1
Component of the mitotic exit network; associates with and is required for the activation and Cdc15p-dependent phosphorylation of the Dbf2p kinase; required for cytokinesis and cell separation; component of the CCR4 transcriptional complex; Functions as an activator subunit for the DBF2 protein kinase. Binds to DBF2, which is required for the phosphorylation and activation of DBF2 by the upstream kinase CDC15 in late anaphase. DBF2-MOB1 is part of the mitotic exit network (MEN) signaling cascade, which regulates release from the nucleus and activity of phosphatase CDC14. Required for i [...] (314 aa)

CDC14
Protein phosphatase required for mitotic exit; required for rDNA segregation, cytokinesis, meiosis I spindle disassembly, environmental stress response; held in nucleolus by Cdc55p in early meiosis, liberated by FEAR and Mitotic Exit Network in anaphase, enabling it to effect a decrease in CDK/B-cyclin activity and mitotic exit; sequestered in metaphase II, released upon entry into anaphase II; human homolog CDC14A can complement thermosensitivity of yeast cdc14-1 mutant; Protein phosphatase which antagonizes mitotic cyclin- dependent kinase CDC28, the inactivation of which is essentia [...] (551 aa)
       
  0.997
TEM1
GTP-binding protein of the ras superfamily involved in termination of M-phase; controls actomyosin and septin dynamics during cytokinesis; GTP-binding protein involved in termination of M phase. May play a role in triggering the degradation of G2 cyclin to inactivate M-phase promoting factor at the termination of mitosis. Acts upstream of CDC15 kinase and may be required to activate the CDC15 protein kinase pathway (245 aa)
       
 
  0.992
CDC15
Protein kinase of the Mitotic Exit Network that is localized to the spindle pole bodies at late anaphase; promotes mitotic exit by directly switching on the kinase activity of Dbf2p; required for spindle disassembly after meiosis II; Protein kinase of the mitotic exit network (MEN) essential for late nuclear division in the mitotic cycle. Promotes mitotic exit by phosphorylating DBF2 and directly switching on DBF2 kinase activity. Involved in the localization of DBF2 and DBF20 to the neck which is necessary to undergo cytokinesis. Plays a role in segregation of chromosomes during recov [...] (974 aa)
     
0.989
CLB2
B-type cyclin involved in cell cycle progression; activates Cdc28p to promote the transition from G2 to M phase; accumulates during G2 and M, then targeted via a destruction box motif for ubiquitin-mediated degradation by the proteasome; Essential for the control of the cell cycle at the G2/M (mitosis) transition. Interacts with the CDC2 protein kinase to form MPF. G2/M cyclins accumulate steadily during G2 and are abruptly destroyed at mitosis (491 aa)
     
 
  0.976
MOB2
Activator of Cbk1p kinase; component of the RAM signaling network that regulates cellular polarity and morphogenesis; activation of Cbk1p facilitates the Ace2p-dependent daughter cell-specific transcription of genes involved in cell separation; simi /.../ Mob1p; Functions as an activator subunit for the CBK1 protein kinase. Part of the regulation of ACE2 activity and cellular morphogenesis (RAM) signaling network. Required for coordinating polarized cell growth during interphase with the onset of mitosis. Required for mother/daughter cell separation after cytokinesis. Also has a role i [...] (287 aa)

SPO12
Nucleolar protein of unknown function, positive regulator of mitotic exit; involved in regulating release of Cdc14p from the nucleolus in early anaphase, may play similar role in meiosis; It is required for meiosis I chromosome division during sporulation. A component of the FEAR (CDC14 early anaphase release) network which promotes CDC14 release from the nucleolus during early anaphase (173 aa)

NET1
Core subunit of the RENT complex, which is a complex involved in nucleolar silencing and telophase exit; stimulates transcription by RNA polymerase I and regulates nucleolar structure; Has a role in chromosome maintenance and is involved in mitotic exit. Inhibits the action of CDC14 by sequestering it in the nucleolus. Also binds to RNA polymerase I and stimulates rRNA synthesis. Influences RDNA chromatin by tethering SIR2 to rDNA in the nucleolus (1189 aa)

CDC55
Non-essential regulatory subunit B of protein phosphatase 2A (PP2A); localization to cytoplasm requires Zds1p and Zds2p and promotes mitotic entry; localization to nucleus prevents mitotic exit; required for correct nuclear division and chromosome segregation in meiosis; maintains nucleolar sequestration of Cdc14p during early meiosis; limits formation of PP2A-Rts1p holocomplexes to ensure timely dissolution of sister chromosome cohesion; homolog of mammalian B55; Phosphatase 2A affects a variety of biological processes in the cell such as transcription, cell cycle progression and cell [...] (526 aa)

SIC1
Inhibitor of Cdc28-Clb kinase complexes that controls G1/S phase transition, preventing premature S phase and ensuring genomic integrity; phosphorylation targets Sic1p for SCF(CDC4)-dependent turnover; functional homolog of mammalian Kip1; Substrate and inhibitor of the cyclin-dependent protein kinase CDC28. Its activity could be important for faithful segregation of chromosomes to daughter cells. It acts in response to a signal from a post-start checkpoint (284 aa)
