Bub1-Bub3 complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.


Summary
Present throughout the cell cycle, this complex promotes spindle assembly checkpoint signalling. The spindle checkpoint ensures accurate chromosome segregation by sending a signal from an unattached kinetochore to inhibit anaphase onset. BUB3 localizes and binds to to kinetochore protein SPC105 via its phosphorylated MELT motif (a motif conforming to the consensus M-[E/D]-[L/I/V/M]-T). The presence of BUB1 positively contributes to the interaction by reducing the BUB3-SPC105 binding affinity.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
