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 (By similarity).
