Functioni

Component of the DASH complex, a microtubule-binding subcomplex of the outer kinetochore that is essential for proper chromosome segregation. The DASH complex mediates the formation and maintenance of bipolar kinetochore-microtubule attachments by forming closed rings around spindle microtubules and establishing interactions with proteins from the central kinetochore. The DASH ring complex may both stabilize microtubules during chromosome attachment in anaphase A, and allow the chromosome to remain attached to the depolymerizing microtubule in anaphase B. Microtubule depolymerization proceeds by protofilament splaying and induces the kinetochore-attached ring to slide longitudinally, thereby helping to transduce depolymerization energy into pulling forces to disjoin chromatids.3 Publications

Interactioni

Subunit structurei

The DASH complex is an approximately 210 kDa heterodecamer, which consists of ASK1, DAD1, DAD2, DAD3, DAD4, DAM1, DUO1, HSK3, SPC19 and SPC34, with an apparent stoichiometry of one copy of each subunit. DASH oligomerizes into a 50 nm ring composed of about 16 molecules that encircles the microtubule. Integrity of the complex and interactions with central kinetochore proteins are regulated by the spindle assembly checkpoint kinase IPL1.1 Publication
