Admin's articles Life Sciences Genome of near-extinct northern white rhino offers hope for reviving the species The northern white rhinoceros is one of the rarest animals on Earth, with just two females left and no natural way for the species to reproduce. Now, an international team of scientists at Scripps Research, the San Diego Zoo Wildlife Alliance, Max Planck Institute for Molecular Genetics, and other collaborators have mapped the entire genome […] Written by Admin May 14, 2025May 14, 2025 Saving Bookmark this article Bookmarked Biology Anillin links up with RhoA to break the symmetry of cytokinetic ring closure During animal cell cytokinesis, active RhoA assembles actomyosin-based contractile rings that tend to close asymmetrically. Through imaging C. elegans zygotes, Lebedev et al. (https://doi.org/10.1083/jcb.202405182) reveal that the scaffold protein, anillin, promotes asymmetric ring closure by locally sequestering RhoA from its canonical effectors and thereby limiting actomyosin contractility.
