Protein: DASH complex subunit SPC34 (34 kDa spindle pole component protein) (Outer kinetochore protein SPC34) (P36131)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: 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.
