MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a kinase involved in spindle checkpoint function. The protein has been localized to the kinetochore and plays a role in the inhibition of the anaphase-promoting complex/cyclosome (APC/C), delaying the onset of anaphase and ensuring proper chromosome segregation. Impaired spindle checkpoint function has been found in many forms of cancer. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous mutant embryos undergo extensive apoptosis and die during early gestation. Heterozygous mice are viable and exhibit splenomegaly, abnormal megakaryopoiesis, and an increased susceptibility to intestinal tumorigenesis. Hypomorphic homozygotes display infertility and premature aging. [provided by MGI curators]
