High impact information on SLI15


Biological context of SLI15

  • These genetic and biochemical studies indicate that Sli15 associates with Ipl1 to promote its function in chromosome segregation [4].
  • The Ipl1-binding and -stimulating activities of Sli15 both reside within a region containing homology to the metazoan inner centromere protein (INCENP) [2].

Anatomical context of SLI15


Associations of SLI15 with chemical compounds

  • Evidence that the Ipl1-Sli15 (Aurora kinase-INCENP) complex promotes chromosome bi-orientation by altering kinetochore-spindle pole connections [5].

Regulatory relationships of SLI15

  • Cdc14 not only regulates mitotic exit but also modulates spindle midzone assembly through Sli15-Ipl1 [3].

Other interactions of SLI15


Analytical, diagnostic and therapeutic context of SLI15

  • This raises the possibility that Ipl1-Sli15 facilitates bi-orientation by promoting turnover of kinetochore-SPB connections until traction of sister kinetochores toward opposite spindle poles creates tension in the surrounding chromatin [5].
