Journal: Nature / Year: 2026 Title: Molecular basis of oocyte cytoplasmic lattice assembly.

CPL comprises subcortical maternal ...Mammalian oocytes are filled with fibric structures called cytoplasmic lattice (CPL) that are essential for oocyte maturation and early embryonic development. CPL comprises subcortical maternal complex (SCMC) and multiple components, including PADI6. Although it was first discovered in the 1960s, the molecular architecture and assembly mechanisms of CPL remain poorly understood. Here we present the cryo-electron microscopy structure of CPL isolated from mouse oocytes. Our analysis identified 14 constitutive protein subunits and revealed that CPL is composed of repeating units comprising U-shaped basket (UB) and adapter ring (AR) features, forming a filamentous architecture. The AR adopts a two-fold symmetric conformation, containing two NLRP4F, four SCMC and two ZBED3 subunits circularized via two distinct interaction clusters. The UB is anchored by PADI6, a didecamer composed of ten homodimers assembled by two back-to-back pentamers, each forming the lateral side of the UB. The underfoot base and up and down sides of the UB are formed by multiple central-symmetric assemblies (UBE2D3-UHRF1-NLRP14) and (TUBB2B-TUBB2A-FBXW24-SKP1), respectively, associating with the PADI6 pentamers to construct the intact UB structure. Two SCMC dimers within each AR connect the up and down sides of two adjacent UBs with an extensive protein-protein interaction network, and thus maintain the repetitive connection between the neighbouring CPL units. Our work unveils the architectural principles underlying the assembly of this large, periodic CPL filament, offering a molecular basis for understanding the functions of CPL in early mammalian embryogenesis and female reproductive disorders.
In the structure databanks used in Yorodumi, some data are registered as the other names, "COVID-19 virus" and "2019-nCoV". Here are the details of the virus and the list of structure data.

EMDB accession codes are about to change! (news from PDBe EMDB page)
The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
The EM Navigator/Yorodumi systems omit the EMD- prefix.

Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
