NET1 mRNA localization to the midbody is required for ARP2/3-dependent initiation of mitotic abscission
The recruitment and activation of abscission machinery following mitosis is tightly spatiotemporally regulated, yet the underlying mechanisms remain poorly understood. We find that RNA localization an...

Ubiquitylation-dependent Rap2 activation regulates lamellipodia dynamics during cell migration - PubMed
Cell migration is a complex process hallmarked by front-to-back cell polarity that is established by the highly dynamic actin cytoskeleton. Branched actin polymerization creates a lamellipodium at the leading edge of the cell, while the contractile acto-myosin cytoskeleton is present at the lagging …

It was a real pleasure to host Daniele Menjivar in my lab as part of CREU program (cancer research experience for undergraduates). It is such a breath of fresh air to be involved in mentoring new generation of scientists, especially in current anti-science environment.
