abstract = {Potassium channel tetramerization domain-containing (KCTD)
proteins are involved in fundamental physio-pathological
processes. Here, we report an analysis of the oligomeric
state of the Bric-à-brack, Tram-track, Broad complex (BTB)
domains of seven distinct KCTDs belonging to five major
clades of the family evolution tree. Despite their
functional and sequence variability, present electron
microscopy data highlight the occurrence of well-defined
pentameric states for all domains. Our data also show that
these states coexist with alternative forms which include
open pentamers. Thermal denaturation analyses conducted
using KCTD1 as a model suggest that, in these proteins,
different domains cooperate to their overall stability.
Finally, negative-stain electron micrographs of
KCTD6$^{BTB}$ in complex with Cullin3 show the presence of
assemblies with a five-pointed pinwheel shape.},
