KAR9

L000002932, YPL269W
Karyogamy protein; required for correct positioning of the mitotic spindle and for orienting cytoplasmic microtubules; localizes at the shmoo tip in mating cells and at the tip of the growing bud in small-budded cells through anaphase

KIN3, KIN31, putative serine/threonine protein kinase KIN4, L000000904, YOR233W
Serine/threonine protein kinase; inhibits the mitotic exit network (MEN) when the spindle position checkpoint is activated; localized asymmetrically to mother cell cortex, spindle pole body and bud neck; KIN4 has a paralog, FRK1, that arose from the whole genome duplication

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Publication

Kin4 kinase delays mitotic exit in response to spindle alignment defects.

Pereira G, Schiebel E

For many polarized cells, it is critical that the mitotic spindle becomes positioned relative to the polarity axis. This is especially important in yeast, where the site of cytokinesis is predetermined. The spindle position checkpoint (SPOC) therefore delays mitotic exit of cells with a mispositioned spindle. One component of the SPOC is the Bub2-Bfa1 complex, an inhibitor of the mitotic ... [more]
