Congratulations to Elvan, Martine, and colleagues on their paper, “Amyloid-like Self-Assembly of a Cellular Compartment,” out now in Cell

New work from a collaboration between the Mitchison lab and our institute is out now in the journal Cell. Elvan Boke and colleagues propose that the Balbiani body, a non-membrane-bound compartment in vertebrate oocytes, is formed by amyloid-like assembly of proteins containing prion-like domains. The Balbiani body contains RNA, mitochondria, and other organelles needed by the early embryo after fertilization. The amyloid-like assembly of prion-like proteins in the Balbiani body (such as Xvelo in Xenopus) may form a protective compartment to help oocytes function as long-lived germ cells. The authors show that Xvelo forms a stable matrix with amyloid-like properties both in vivo and in vitro and that the association of Xvelo with the Balbiani body is dependent on Xvelo’s prion-like domain.

Congratulations to Elvan, our postdoc Martine Ruer, and the whole team!
