Mechanism of centromere recruitment of the CENP-A chaperone HJURP and its implications for centromere licensing

The CENP-A chaperone HJURP associates with Mis18α, Mis18β, and M18BP1 to target centromeres and deposit new CENP-A. Here the authors provide evidence that two repeats in human HJURP previously proposed to be functionally distinct are interchangeable and bind concomitantly to the 4:2:2 Mis18α:Mis18β:M18BP1 complex without dissociating it.
