News from Cytoskeleton Research Laboratory

30 June 2020

Ozge, Onur and Can’s paper is now online in PLOS Biology! We used chemical manipulation to target centriolar satellites to the cell periphery or center and then asked what happens. We showed that pericentrosomal satellite clustering is important for cilium assembly, maintenance and disassembly as well as mitosis.

3 June 2020

New review paper from the lab is out in MDPI Cells. We have been meaning to write this review for a while, the self-isolation due to COVID-19 finally gave us the time to write a comprehensive review on the application of proximity-based labeling approaches to the centrosome/cilium complex. BioID has been special for our lab as it paved the way to many different ongoing research projects.

12 May 2020

New paper from the lab is out in Cell Reports! In this paper, we reported CCDC57 as a pleiotropic regulator of centriole duplication, mitosis and cilium assembly. Our cover was not selected for the issue, but we all loved it. Thank you Deniz Conkar for preparing it.

Firat-Karalar lab will come back with full pace once our lab opens.
