It’s a kar9ochore to capture microtubules

Microtubule orientation to cortical spatial cues is essential for the fidelity of asymmetric cellular processes. A cortical microtubule-capture site, composed of Bim1 and Kar9, has now been identified in yeast. Bim1 is the yeast homologue of EB1, a binding partner of the adenomatous polyposis coli (APC), indicating that important features of this complex may be highly conserved.
