STRINGSTRING
KAR1 protein (Saccharomyces cerevisiae) - STRING interaction network
"KAR1" - Essential protein involved in karyogamy during mating and in spindle pole body duplication during mitosis, localizes to the half-bridge of the spindle pole body, interacts with Spc72p during karyogamy, also interacts with Cdc31p 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

KAR1Essential protein involved in karyogamy during mating and in spindle pole body duplication during mitosis, localizes to the half-bridge of the spindle pole body, interacts with Spc72p during karyogamy, also interacts with Cdc31p; KAR1 is required for function of both intranuclear and extranuclear microtubules. KAR1 helps localize CDC31 to the spindle pole body (SPB), CDC31 then initiates SPB duplication via interaction with a downstream effector (433 aa)    
Predicted Functional Partners:
CDC31
Calcium-binding component of the spindle pole body (SPB) half-bridge, required for SPB duplication in mitosis and meiosis II; homolog of mammalian centrin; binds multiubiquitinated proteins and is involved in proteasomal protein degradation; Functions as a component of the nuclear pore complex (NPC) and the spindle pole body (SPB) half-bridge. At the SPB, it is recruited by KAR1 and MPS3 to the SPB half-bridge and involved in the initial steps of SPB duplication. It probably plays a similar role in de novo assembly of NPCs at the nuclear envelope. Also involved in connection with the p [...] (161 aa)

SPC72
Component of the cytoplasmic Tub4p (gamma-tubulin) complex, binds spindle pole bodies and links them to microtubules; has roles in astral microtubule formation and stabilization; Spindle pole body component that acts as the gamma- tubulin complex-binding protein of the SPB outer plaque. Anchors cytoplasmic microtubules at the at the half bridge of the spindle pole body (SPB) and accordingly functions in nuclear position and spindle orientation, including anaphase spindle migration into the bud. Recruits KIN4 kinase to both SPBs when cytoplasmic microtubules are defective. Links cytopla [...] (622 aa)

BBP1
Protein required for the spindle pole body (SPB) duplication, localized at the central plaque periphery; forms a complex with a nuclear envelope protein Mps2p and SPB components Spc29p and Kar1p; required for mitotic functions of Cdc5p; Component of the spindle pole body (SPB) required for insertion of the nascent SPB into the nuclear envelope and for the proper execution of spindle pole body (SPB) duplication. Connects the central plaque of the SPB with the half-bridge. Required for proper localization of CDC5 at the SPB and for proper M-phase progression (385 aa)
     
 
  0.901
SFI1
Centrin (Cdc31p)-binding protein required for spindle pole body (SPB) duplication, localizes to the half-bridge of the SPB, required for progression through G(2)-M transition, has similarity to Xenopus laevis XCAP-C; Component of the spindle pole body (SPB) half-bridge involved in the initial steps of SPB duplication (946 aa)
     
 
  0.895
SPC98
Component of the microtubule-nucleating Tub4p (gamma-tubulin) complex; interacts with Spc110p at the spindle pole body (SPB) inner plaque and with Spc72p at the SPB outer plaque; Involved in microtubule organization by the microtubule organizing center, the spindle pole body (SPB). Probably part of the microtubule attachment site at the SPB (846 aa)
       
 
  0.890
TUB4
Gamma-tubulin, involved in nucleating microtubules from both the cytoplasmic and nuclear faces of the spindle pole body; Tubulin is the major constituent of microtubules. The gamma chain is found at microtubule organizing centers (MTOC) such as the spindle poles or the centrosome, suggesting that it is involved in the minus-end nucleation of microtubule assembly. TUB4 is an important spindle pole body component that organizes both cytoplasmic and nuclear microtubule arrays (473 aa)

SPC97
Component of the microtubule-nucleating Tub4p (gamma-tubulin) complex; interacts with Spc110p at the spindle pole body (SPB) inner plaque and with Spc72p at the SPB outer plaque; Involved in microtubule organization by the microtubule organizing center, the spindle pole body (SPB). Probably part of the microtubule attachment site at the SPB (823 aa)

CNM67
Component of the spindle pole body outer plaque; required for spindle orientation and mitotic nuclear migration; Involved in the pathway that organizes the shaping and sizing of the prospore membrane (PSM) during sporulation. Required for the proper formation of the spindle pole body (SPB) outer plaque. May connect the outer plaque to the central plaque embedded in the nuclear envelope (581 aa)

SPC24
Component of the evolutionarily conserved kinetochore-associated Ndc80 complex (Ndc80p-Nuf2p-Spc24p-Spc25p); involved in chromosome segregation, spindle checkpoint activity and kinetochore clustering; Acts as a component of the essential kinetochore- associated NDC80 complex, which is involved in chromosome segregation and spindle checkpoint activity (213 aa)

SPC29
Inner plaque spindle pole body (SPB) component, links the central plaque component Spc42p to the inner plaque component Spc110p; required for SPB duplication; Component of the spindle pole body (SPB) required for the proper execution of spindle pole body (SPB) duplication. Links the central plaque component SPC42 to the inner plaque component SPC110 (253 aa)
