Disease

[CASC5_HUMAN] Autosomal recessive primary microcephaly. A chromosomal aberration involving CASC5 is associated with acute myeloblastic leukemia (AML). Translocation t(11;15)(q23;q14) with KMT2A/MLL1. May give rise to a KMT2A/MLL1-CASC5 fusion protein. The disease is caused by mutations affecting the gene represented in this entry.

Function

[CASC5_HUMAN] Performs two crucial functions during mitosis: it is essential for spindle-assembly checkpoint signaling and for correct chromosome alignment. Required for attachment of the kinetochores to the spindle microtubules. Directly links BUB1 and BUB1B to kinetochores. Part of the MIS12 complex, which may be fundamental for kinetochore formation and proper chromosome segregation during mitosis. Acts in coordination with CENPK to recruit the NDC80 complex to the outer kinetochore.[1] [2] [3]
