Zw10 protein, in the context of the conserved Rod-Zwilch-Zw10 (RZZ) complex, is required for correct metaphase check-pointing during mitosis [1,2] and it is also important in vesicle transport between Golgi and ER as part of a second complex together with the conserved conserved RINT1/Tip20p and NAG/Sec39p proteins [3]. Zw10 is the metazoan homologue of yeast Dsl1, and are included in the complexes associated with tethering containing helical rods (CATCHR) family, sharing structural features [3,4]. This entry represents the middle domain of zw10, which, from AlphaFold prediction, consists of four beta-strands and four alpha-helices.
