<Daiju Kitagawa> led work explaining the ninefold organization of <centrioles> through interactions between <SAS-6> molecules. The 2011 study combined structural analysis, biochemical assembly and cellular experiments: rod-shaped dimers associated through their ends, and disrupting the relevant association impaired centriole formation.<Structural basis of the 9-fold symmetry of centrioles by Daiju Kitagawa and others>[Summary: SAS-6 oligomerization and centriole formation]{ref}
A model built from the related <Chlamydomonas reinhardtii> <protein> placed nine dimers in a ring with spokes extending outward. Recombinant <protein> also formed cartwheel-like assemblies. The work connects a repeated <protein structure> to the larger geometry of an <organelle>, rather than treating its symmetry as an unexplained cellular pattern.<Structural basis of the 9-fold symmetry of centrioles by Daiju Kitagawa and others>[Summary and structural model of Bld12p]{ref}
