Amgen Scholars: Announcements of Opportunity

Below are Announcements of Opportunity posted by Caltech faculty for the Amgen Scholars program.

Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions! Remember: This is just one way that you can go about identifying a suitable project and/or mentor. For additional tips on identifying a mentor click here.

Please remember:

  • Students pursuing Amgen must be U.S. citizens, U.S. permanent residents, or students with DACA status.
  • Students pursuing Amgen must complete the 10-week program from June 18 - August 23, 2024. Students must commit to these dates. No exceptions will be made.
  • Accepted students must live in provided Caltech housing.

Project:  Structural and Function Characterization of Mega Assemblies
Disciplines:  Biochemistry, Structural Biology, Cell Biology
Mentor:  Andre Hoelz, Professor of Chemistry and Biochemistry, (CCE),, Phone: 626-395-8480
Mentor URL:  (opens in new window)
Background:  In eukaryotic cells, the spatial segregation of replication and transcription in the nucleus and transition in the cytoplasm imposes the requirement of transporting thousands of macromolecules between these two compartments. Nuclear pore complexes (NPCs) are the sole gateways that facilitate this macromolecular exchange across the nuclear envelope with the help of soluble transport receptors. Whereas the mobile transport machinery is reasonably well understood at the atomic level, a commensurate structural characterization of the NPC has not been achieved.

Our lab carries out structure-function studies of the nuclear pore complex with the ultimate goal of elucidating its entire atomic structure - the applied structure determination as well as the design principles.
Description:  The student will work with a graduate student or postdoctoral fellow to purify and crystallize protein complexes and to carry out functional analyses in yeast.
