High impact information on CIK1

 

Biological context of CIK1

 

Anatomical context of CIK1

  • The Cik1p::beta-gal fusion does not localize to the SPB or microtubules in a kar3 delta strain, and the Kar3p::beta-gal fusion protein does not localize to microtubule-associated structures in a cik1 delta strain [8].
 

Associations of CIK1 with chemical compounds

 

Other interactions of CIK1

  • Localization of the Kar3 kinesin heavy chain-related protein requires the Cik1 interacting protein [8].
  • Consistent with its mutant phenotype, we found that the kar4 mutation resulted in failure to induce KAR3 and CIK1 mRNA during mating [6].
  • ROM2 and RHO2 were identified in a screen for high-copy number suppressors of cik1 delta, a mutant defective in microtubule-based processes in Saccharomyces cerevisiae [10].
 

Analytical, diagnostic and therapeutic context of CIK1

  • Analysis by both the two-hybrid system and co-immunoprecipitation experiments indicates that Cik1p and kar3p interact, suggesting that they are part of the same protein complex [8].
  • The dependence of Cik1p and Kar3p localization upon one another was investigated by indirect immunofluorescence of fusion proteins in pheromone-treated cells [8].
  • Sequence analysis of the CIK1 gene predicts that the CIK1 protein is 594 amino acids in length and possesses a central 300-amino-acid coiled-coil domain [1].
