General Information
Term Bfa1-Bub2 complex ID (Ontology) GO:1990334 (Gene Ontology)
Definition A protein complex that acts as a two-component GTPase-activating protein for Tem1 GTPase, thus regulating a signal transduction cascade, called the mitotic exit network (MEN), which is required for mitotic exit and cytokinesis. Bub2/Bfa1 keeps Tem1 inactive until the spindle is properly oriented, thus inhibiting MEN activation.[ PubMed:16449187 ]
