La serina/treonina cinasa de punto de control mitótico BUB1 beta (BUB1B) es una enzima codificada en humanos por el gen HGNC BUB1B .

Este gen codifica una cinasa implicada en la función del punto de control de la mitosis o del ensamblaje del huso mitótico. Esta proteína ha sido localizada en el cinetocoro y juega un importante papel en la inhibición del complejo promotor de la anafase/ciclosoma (APC/C), retrasando la entrada en anafase y asegurando una correcta segregación de los cromosomas. Se has asociado diversos tipos de cáncer con anomalías encontradas en la función del punto de control del huso mitótico.

Esta enzima pertenece a la familia de las serina/treonina proteína cinasas no específicas (EC 2.7.11.1).
