Our new paper is now online: doi.org/10.1242/jcs.264478. We describe how kinetochore proteins, essential for chromosome segregation, form linear elements in the cytoplasm and have a previously unrecognized role in vesicle transport! Check out our movies!

🚨 Our new @eLife study dissects how a dividing cell keeps its septin scaffold and its contractile ring in step. 👉 elifesciences.org/articles/1… Stellar work by @BinduBhojappa 👏 funded by @India_Alliance @ANRFIndia @iiscbangalore #septin #yeast #celldivision #cytokinesis

Annulate lamellae – an underexplored cellular structure

Summary: This Review discusses insights into the structure, biogenesis and functional relevance of annulate lamellae – endoplasmic reticulum subdomains harbouring a subset of nucleoporins.

Basal bodies (BBs) are what eventually become motile cilia. So, if they don't get positioned correctly on the apical surface, the whole tissue level function can go wrong → ciliopathies. We know actin is involved… but how does it actually control this process? 🤔 (3/17)

Yang et al show that #Celegans CKS-1 is required, w/ CDK-1, for #anaphase B during oocyte #meiosis I; promotes anaphase onset thru. securin & cyclin B1 destruction in meiosis I & II, respectively; & acts positively w/ both securin & cyclin B3 in meiosis II hubs.la/Q03_WFhj0

Spotlight: Moghareh, Bojorquez, and Lara-Gonzalez @ucirvine highlight work from Yang et al. (hubs.la/Q03_WPfB0) showing that CKS-1 plays key roles in both #anaphase B during #oocyte #meiosis I and the #metaphase II–to–anaphase II transition. hubs.la/Q03_WP970

Cell division, the physical separation of a cell into two daughter cells, is classically thought to require continuous plasma membrane invagination driven by equatorial contractile forces. Here, we...

How is timely and accurate sister chromatid separation achieved? A process that is happening around 30-50 billion times per minute!!! in the human body needs tight regulation (to avoid cancer development...). paper: lnkd.in/eHCYuyhc comment: lnkd.in/ezyw2dxi

Been doing a lot of time lapses of iPSC-derived cardiac muscle cells lately! Here's one of my favorites. This cell is expressing fluorescent alpha-actinin-2 and the colors represent depth. Movie length = 24h with frames taken every 20m. #microscopymonday #cellbiology @MAG2ART

The nuclear localization of Ect2 is required for cytokinesis biorxiv.org/content/10.1101/… #biorxiv_cellbio

The nuclear localization of Ect2 is required for cytokinesis

In cytokinesis, a contractile ring constricts the cell to form two daughters. After ingression, the ring matures into the midbody, and an intercellular bridge connects the daughter cells until it is...
