Cell Symposia: Biological Assemblies: Phase Transitions and More
November 1–3, 2021 | ONLINE LIVE & ON-DEMAND

As the future situation regarding international travel remains uncertain, we have made the decision to switch the Cell Symposia: Biological Assemblies: Phase Transitions and More to our fully interactive online conference platform, which will take place November 1–3.

The online program will include access to the same great content planned for our in-person event with presentations from our invited speakers together with contributed talks and ePosters – all available on-demand for 6 months after the event. You can stream this interactive conference experience live from your desktop or mobile device and connect during the event with speakers and other attendees.

For more information about our online conferences, please refer to 'What to Expect' and FAQs.

About the symposia

For many years, our understanding of the organization of major biological activities within the cell was limited to membrane-dependent compartmentalization. However, over the past few years a revolution in thought has been sweeping nearly the entire cell biology community. It is now becoming clear that many complex functions of the cell, and the multiple biochemical complexes that perform them, are highly organized and coordinated in non-membrane-bound molecular compartments. In some cases, we are uncovering the regulation and function of long-mysterious subcellular assemblages. In other cases, we are only beginning to appreciate that known biological activities function through organized structures.

We hope you can join us online, where we will connect researchers across the breadth of cell biology studying the regulation and consequences of organization of large biological complexes throughout the cell. The focus will be on bringing together researchers working across the cell biology spectrum, including the cytoskeleton, stress granules, signaling clusters, the nuclear pore, transcription centers, chromatin, and more. Emerging concepts and technologies with broad applicability will be emphasized to help cross-pollinate new avenues of research for the diverse interests of conference attendees.

Topics within the scope of this meeting include, but are not limited to:

The roles and mechanisms of organizing molecules

  • RNA versus protein
  • Disordered protein regions and multivalent interactions
  • Phase transitions and hydrogels

Organization in the nucleus

  • Chromatin and heterochromatin
  • Paraspeckles and nucleoli
  • DNA damage foci

Organization in the cytoplasm and within and around membranes

  • Subcellular granules and functional amyloid-like structures
  • Signalosomes, cytoskeleton,and nuclear pores
  • Synaptic and post-synaptic densities
  • Juxta-endomembrane assemblies

Functional and mechanistic dissection of roles in basic cell biology and development

  • Autophagy, innate immune, and other cell stress responses
  • DNA transactions: transcription, DNA repair, and genome stability
  • Germ cell and embryonic development

Functional and mechanistic dissection of roles in disease

  • Cancer
  • Neurodegeneration
  • Other protein misfolding disorders

Our online platform will allow you to:

  • Easily navigate the programme and live-stream sessions and presentations
  • Upload your poster presentation and network and chat with attendees
  • Engage live with other attendees and speakers through chats, polls, virtual networking meetings and more
  • Invite attendees to one-on-one meetings using an integrated appointment schedule
  • Access the event via any device–mobile, tablets or desktop
  • Access all content of the conference on-demand for 6 months
