Our review article “The emerging roles of non-canonical ubiquitination in proteostasis and beyond” became open online.

Fumiyo as an editorial board member of the JCB organized and wrote together with Stephanie Kaypee (our postdoc), Fumiaki Ohtake and Yoshino Akizuki (the Ohtake Lab).

The Ohtake lab has expertise in the ubiquitin chains called branched chains. We tried to combine our expertise on linear ubiquitination with theirs in this article.

We believe that we covered the most exciting topics from the ubiquitin biology reserach field.

It was a lot of fun writing this with people with slightly different expertise!

 

Did you know that ubiquitination targets are not limited to proteins?

A new mini-review by Fumiyo is out now in the journal of American Journal of Physiology-Cell Physiology (an accepted version of the mansucript).

Fumiyo wrote  a short review article with Fuminori Tokunaga (Osaka City Univ) describing how defect of linear ubiquitination induced by LUBAC may correlate with human diseases such as autoimmunes and neurodegenerative diseases. We also disucssed potential applications of LUBAC inhibitors.

Our work on “The ubiquitin ligase HOIL-1L regulates immune responses by interacting with linear ubiquitin chains” is now online (iScience). Carlos, the last PhD student of the Ikeda Lab at IMBA (Austria) did a great job here.

The Ikeda lab (MIB, Japan and IMBA, Austria) and the Haselbach lab (IMP,  Austria) published a paper entitled “The linear ubiquitin chain assembly complex LUBAC generates heterotypic ubiquitin chains” in eLife.

In this study, we found that LUBAC generates heterotypic ubiquitin chains (oxyester bond-based branching on the linear ubiquitin chains) dependently on the catalytic site in the HOIL-1L RING2 domain. We also revealed the first 3D structural model of an E3 ligase complex called LUBAC.

This was a work of Alan of his PhD study. Congratulations to everyone who was involved!
