Cytoplasmic lattices are megadalton storage complexes in mammalian oocytes
Mammalian oocytes store proteins for embryonic development on abundant structures known as cytoplasmic lattices (CPLs)1; however, the mechanisms by which they achieve this are unclear, largely because the molecular composition of the lattices themselves is unknown. Here, we use cryo-electron microscopy and artificial intelligence-based modeling to elucidate the molecular architecture and protein composition of native…
