Samed Delic received a Poster Award

Samed’s poster on Chlamydomonas septin and the evolution of this family of proteins in eukaryotes received  a poster award at the Triangle Cytoskeleton Meeting. Congrats Samed! https://www.trianglecytoskeleton.com

Yaning Yuan joined the lab

Yaning arrived at Duke to attend the Biology Program. Welcome Yaning!

Rossie Clark-Cotton joined the lab

Rossie graduated from the Department of Cell Biology at Duke, where she studied the mechanism of cell-cell fusion and chemotropism using budding yeast. She joins the lab as a visiting postdoc from Stanford University. Welcome Rossie!

Cleavage-furrow formation without F-actin – new publication in PNAS

A new paper on cytokinesis in Chlamydomonas has been published in PNAS. https://doi.org/10.1073/pnas.1920337117 In this paper, we demonstrated that F-actin is enriched in the cleavege-furrow region of dividing Chlamydomonas cells by using Lifeact marker.  Interestingly, however, there is no myosin co-localizing with F-actin in the furrow, suggesting that no “actomyosin” structure is directly involved in …

New on bioRxiv: Our paper on Furrowing without F-actin

Cleavage-furrow formation without F-actin in Chlamydomonas Masayuki Onishi, James G Umen, Frederick R Cross, John R Pringle https://www.biorxiv.org/content/10.1101/789016v1

Onishi Lab is Opening in January 2020!

We will investigate the fundamental core mechanisms of cytokinesis and their evolution from the common ancestors, using Chlamydomonas in our lab, and with collaborators who use other systems.  Join us for this exciting expedition!!

Septins, cytokinesis, and ER stress – Collaboration paper
