STRINGSTRING
CIK1 protein (Saccharomyces cerevisiae) - STRING interaction network
"CIK1" - Kinesin-associated protein required for both karyogamy and mitotic spindle organization, interacts stably and specifically with Kar3p and may function to target this kinesin to a specific cellular role 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

CIK1Kinesin-associated protein required for both karyogamy and mitotic spindle organization, interacts stably and specifically with Kar3p and may function to target this kinesin to a specific cellular role; has similarity to Vik1p; A developmentally regulated protein important for microtubule functions. Targets KAR3 to the cytoplasmic microtubules during mating. Essential for KAR3 function during prophase of meiosis I. Required for interhomolog recombination, synapsis of homologous chromosomes and establishment of a meiosis I spindle (594 aa)    
Predicted Functional Partners:
KAR3
Minus-end-directed microtubule motor; functions in mitosis and meiosis, localizes to the spindle pole body and localization is dependent on functional Cik1p, required for nuclear fusion during mating; potential Cdc28p substrate; Essential for yeast nuclear fusion during mating. KAR3 is a bifunctional protein having a kinesin-like motor domain joined to a distinct microtubule binding domain. It may mediate microtubule sliding during nuclear fusion and possibly mitosis. May interact with spindle microtubules to produce an inwardly directed force acting upon the poles. KAR3 function antag [...] (729 aa)

VIK1
Protein that forms a complex with Kar3p at the spindle pole body, possible regulator of Kar3p function in microtubule-mediated processes; required for sister chromatid cohesion; has similarity to Cik1p; Targets and/or maintains KAR3 at the spindle pole body during vegetative growth (647 aa)
       
0.970
KIP3
Kinesin-related motor protein involved in mitotic spindle positioning (805 aa)
       
  0.965
KIP1
Kinesin-related motor protein required for mitotic spindle assembly, chromosome segregation, and 2 micron plasmid partitioning; functionally redundant with Cin8p for chromosomal but not plasmid functions; Required for assembly of the mitotic spindle. Interact with spindle microtubules to produce an outwardly directed force acting upon the poles. Following spindle assembly, CIN8 and KIP1 apparently act to oppose a force that draws separated poles back together. This force seems to be mediate by KAR3 (1111 aa)
         
  0.956
KIP2
Kinesin-related motor protein involved in mitotic spindle positioning, stabilizes microtubules by targeting Bik1p to the plus end; Kip2p levels are controlled during the cell cycle; Required for assembly of the mitotic spindle (706 aa)
         
  0.952
ATG31
Autophagy-specific protein required for autophagosome formation; may form a complex with Atg17p and Atg29p that localizes other proteins to the pre-autophagosomal structure; high-copy suppressor of CIK1 deletion; Plays a role in starvation-induced autophagy. Involved in mitophagy. Functions with ATG17 and ATG29 at the preautophagosomal structure (PAS) in order to form normal autophagosomes under starvation conditions. May be involved in microtubule function, such as chromosome segregation and karyogamy (196 aa)
       
 
  0.874
CIN8
Kinesin motor protein involved in mitotic spindle assembly and chromosome segregation; Required for assembly of the mitotic spindle. Interacts with spindle microtubules to produce an outwardly directed force acting upon the poles. Following spindle assembly, CIN8 and KIP1 apparently act to oppose a force that draws separated poles back together. This force seems to be mediated by KAR3 (1000 aa)
       
  0.873
BIK1
Microtubule-associated protein, component of the interface between microtubules and kinetochore, involved in sister chromatid separation; essential in polyploid cells but not in haploid or diploid cells; ortholog of mammalian CLIP-170; Required for nuclear fusion, chromosome disjunction, and nuclear segregation during mitosis. Probably required for the formation or stabilization of microtubules during mitosis and for spindle pole body fusion during conjugation (440 aa)
       
 
  0.835
ASK1
Essential subunit of the Dam1 complex (aka DASH complex), couples kinetochores to the force produced by MT depolymerization thereby aiding in chromosome segregation; phosphorylated during the cell cycle by cyclin-dependent kinases; Component of the DASH complex, a microtubule-binding subcomplex of the outer kinetochore that is essential for proper chromosome segregation. The DASH complex mediates the formation and maintenance of bipolar kinetochore-microtubule attachments by forming closed rings around spindle microtubules and establishing interactions with proteins from the central ki [...] (292 aa)
       
 
  0.754
MAD1
Coiled-coil protein involved in the spindle-assembly checkpoint; phosphorylated by Mps1p upon checkpoint activation which leads to inhibition of the activity of the anaphase promoting complex; forms a complex with Mad2p; Central component of the spindle assembly checkpoint. Thought to recruit MAD2 to unattached kinetochores. During checkpoint activity, MAD2 is relayed from the MAD1-MAD2 complex to the mitotic checkpoint complex (MCC). The formation of a MAD1- BUB1-BUB3 complex seems to be required for the spindle checkpoint mechanism (749 aa)
