39th Symposium: Iron-Sulfur Proteins—Biogenesis, Regulation and Function

39th symposium logo

May 29 through June 2, 2018 at Memorial Union

This international meeting is the latest in a series that convened last in Bergamo, Italy in 2015. The symposium will bring together leading scientists in the field of iron–sulfur proteins to discuss their most recent research activities.

  • Fe–S cluster assembly and transfer
  • Compartmentalization of Fe–S protein biogenesis
  • Assembly of clusters in multisubunit complexes
  • Iron trafficking, regulation, and sensing
  • Regulation of Fe–S protein biogensis
  • Disease-associated Fe–S protein defects
  • Fe–S proteins: atypical clusters, novel chemistry, and new roles and functions
  • Engineering and evolution of Fe–S proteins

This is an accordion element with a series of buttons that open and close related content panels.

Poster Info

Maximum size: 4 ft (122 cm) x 4 ft (122 cm)

Pins will be provided.

Posters should be set up before 2:00 PM on Wednesday, May 30th.

Posters must be taken down by 3:30 PM on Saturday, June 2nd.

— LIGHTNING PRESENTATIONS – Pre-Poster Sessions 1 & 2 —

“To promote the research that will be presented during the poster sessions, we have scheduled time right before each of the first two poster sessions for lightning poster presentations. If you choose to participate, poster presenters should prepare 1 slide to present a 1 min highlight of their poster findings. The author should focus only on the main aim of the research and the major findings since the purpose of a “lightning presentation” is to give the audience the “major take-home message” from your poster, NOT to present all of the results. These presentations should stimulate the audience to view the poster and to discuss the research with the author during the breaks or poster session.

Email your one summary slide to steenbock39@union.wisc.edu by Tuesday, May 22nd, by 5pm.”
