What pLDDT means and how to read it

Function

Component of the DASH complex that connects microtubules with kinetochores and couples microtubule depolymerization to chromosome movement; it is involved in retrieving kinetochores to the spindle poles before their re-orientation on the spindle in early mitosis and allows microtubule depolymerization to pull chromosomes apart and resist detachment during anaphase (PubMed:15664196, PubMed:16415853, PubMed:16777964, PubMed:17460120, PubMed:17643123). Kinetochores, consisting of a centromere-associated inner segment and a microtubule-contacting outer segment, play a crucial role in chromosome segregation by mediating the physical connection between centromeric DNA and microtubules…

Subunit structure

Component of the DASH complex consisting of ASK1, DAD1, DAD2, DAD3, DAD4, DAM1, DUO1, HSK3, SPC19 and SPC34, with a stoichiometry of one copy of each subunit per complex (PubMed:11782438, PubMed:15640796, PubMed:16715078, PubMed:17460120, PubMed:17643123, PubMed:25236177). Multiple DASH complexes oligomerize to form a ring that encircles spindle microtubules and organizes the rod-like NDC80…
