Bub3 Gene Summary [Rat]
Predicted to be involved in attachment of spindle microtubules to kinetochore; protein localization to kinetochore; and regulation of chromosome segregation. Predicted to be located in kinetochore and nucleoplasm. Predicted to be part of mitotic checkpoint complex. Orthologous to human BUB3 (BUB3 mitotic checkpoint protein).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Bub3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
