摘要
Histones are among the most conserved proteins in eukaryotes: the structural constraints of the nucleosome pose a challenge to evolving novel function. Nevertheless, confined histone surfaces have diversified, allowing the modulation of basic chromatin function through specialized histone chaperones. Recent structures of three histone-chaperone complexes, DAXX, HJURP, and Scm3, exemplify a common parsimonious solution to the restricted evolutionary space of histone recognition by their cognate histone chaperones: the reutilization of existing themes in histone structural biology.
