Papain-like protease (PLpro) from SARS-CoV-2 plays essential roles in the replication cycle of the virus that is the cause of the global COVID-19 pandemic. In human cells that the virus has infected, PLpro seeks out and binds with the interferon-stimulated gene 15 (ISG15) protein, a key component of the cells’ immune response. PLpro strips ISG15 from other cellular proteins to aid SARS-CoV-2 in evading the body’s immune system.

Scientists at Oak Ridge National Laboratory (ORNL) used small-angle neutron scattering (SANS) at the High Flux Isotope Reactor (HFIR) combined with computational techniques to reveal the molecular details of how the two proteins interact. Susan Tsutakawa, a staff scientist in the Molecular Biophysics and Integrated Bioimaging (MBIB) Division, obtained small-angle x-ray scattering (SAXS) data on the PLpro-ISG15 complex at Berkeley Lab’s Advanced Light Source (ALS) to augment the SANS work.

An imaging technique pioneered by Berkeley Lab is helping reveal the best antibodies to test for in rapid and reliable COVID-19 detection. Although current tests such as polymerase chain reaction (PCR) are highly accurate, these samples must be sent to an accredited lab for testing, causing a longer wait time for results. Michal Hammel, a research scientist in the Molecular Biophysics and Integrated Bioimaging Division, and Curtis D. Hodge led a study that could help get reliable, self-administered tests with instant results on the market.

The projects of 17 Biosciences Area scientists and engineers received funding through the FY22 Laboratory Directed Research and Development (LDRD) program.

Four Biosciences employees were selected by Berkeley Lab leadership and the Women Scientists and Engineers Council (WSEC) for recognition as part of the 2020 Women @ the Lab awards. The biennial program, now in its fourth year, spotlights women at the Lab for meritorious professional contributions, leadership, mentorship, and outreach.

In the latest episode of JGI’s monthly podcast, Genome Insider, Alison Takemura interviews Setsuko Wakao and Kris Niyogi, biologists at UC Berkeley and in Berkeley Lab’s Molecular Biophysics and Integrated Bioimaging (MBIB) Division. In this 20-minute episode, they discuss their research on a tiny group of algae with insanely gorgeous exterior shells.
