General Information

Term

mitotic spindle assembly checkpoint signaling

ID (Ontology)

GO:0007094 (Gene Ontology)

Definition

A mitotic cell cycle checkpoint that delays mitotic sister chromatid separation and consequently the mitotic metaphase/anaphase transition until the spindle is correctly assembled and chromosomes are attached to the spindle. Spindle assembly checkpoint signaling begins with the activated Mph family kinase, and results in the inhibition of the Anaphase Promoting Complex and its activator Sleepy/Cdc20 by the mitotic checkpoint complex (MCC).[ PubMed:12360190 ]

Also Known As

"mitotic cell cycle spindle assembly checkpoint" ; "mitotic checkpoint" ; "mitotic spindle assembly checkpoint" (for all, see Synonyms field below)
