Also known as: YEB1
Summary: Enables microtubule plus-end binding activity. Involved in several processes, including 2-micrometer plasmid partitioning; mitotic spindle orientation checkpoint signaling; and regulation of microtubule polymerization or depolymerization. Acts upstream of or within microtubule nucleation. Located in microtubule cytoskeleton. Human ortholog(s) of this gene implicated in congenital symmetric circumferential skin creases 2. Orthologous to human MAPRE1 (microtubule associated protein RP/EB family member 1); MAPRE2 (microtubule associated protein RP/EB family member 2); and MAPRE3 (microtubule associated protein RP/EB family member 3).

the microtubule-associated proteins Bik1 and Bim1 are important host factors in the process of plasmid localization to a certain sub-nuclear locale probably assisted by the motor protein, Kip1 and microtubules, perhaps by acting as an adapter between the plasmid and the motor and thus helping to anchor the plasmid to microtubules.
