RESEARCH

IPD Translational Investigator, Dr. Ingrid Pultz, published a paper in JACS  this month titled ‘Engineering of Kuma030: A Gliadin Peptidase That Rapidly Degrades Immunogenic Gliadin Peptides in Gastric Conditions‘.Kuma030 Using Rosetta to redesign the active site of the gliadin protease KumaMax – an enzyme computationally designed to break down gluten in the stomach – Dr. Pultz and collaborators show that the new variant Kuma030 degrades >99% of the gluten peptide that triggers inflammation in celiac disease patients. This work brings us even closer to arriving at an oral therapeutic for celiac disease.

IN THE NEWS

Dr. Pultz was interviewed by MyNorthwest.com on her work developing a pill that celiac patients can take before consuming gluten. Read and hear more at the link:

INSTITUTE

The IPD hosted its second Scientific Council meeting this month, chaired by David Urdal, PhD, MS. The council is made up of UW and Fred Hutch faculty from a variety of departments (Oncology, Genome Sciences, Immunology, Allergy & Infectious Diseases, Biochemistry, and Pharmacology). The goal of the IPD Scientific Council is threefold:
1. Identify new opportunities, targets, and applications to which protein design can be applied
2. To strategize on how best to balance core technology development with translational projects of value today and translational projects with important impacts 5 to 10 years down the road
3. Provide feedback on current projects

IPD Director Dr. David Baker was the Keynote speaker at the 13th Annual NanoDDS (International Nanomedicine and Drug Delivery) symposium, held at the UW this year. Dr. Baker gave a talk entitled ‘Engineering Protein Nanocarriers: Deisgn of protein interaction inhibitors and self-assembling nanocages’.

Dr. Baker also spoke on a panel at the Washington State Academy of Sciences 8th Annual Symposium on “Accelerating Science’s Impact: Translating Discoveries Into Solutions”. Held at the Museum of Flight, the panel was moderated by UW CoMotion Executive Director Vikram Jandhlaya and panelists discussed various topics under the theme of “Translational Science for Health and Disease Barriers and Solutions”.

RESEARCH

Following the groundbreaking 2014 Nature paper describing the development of a computational method to design multi-component coassembling protein nanoparticles, comes a publication in Protein Science from Baker lab graduate student Jacob Bale and collaborators. Titled “Structure of a designed tetrahedral protein assembly variant engineered to have improved soluble expression“, the paper reports a variant of a previously low yielding tetrahedral designed material for which structure determination was difficult. The new variant described in the paper had a much improved yield after redesign and the structure obtained agreed with the computational model with high atomic-level accuracy. The methods used here to improve soluble protein yield will be generally applicable to improving the yield of many designed protein nanomaterials.

INSTITUTE

Congratulations to newly minted PhDs and graduates of the Baker lab Dr. Shawn Yu and Dr. Ray Wang! Both defended their dissertations this month. Dr. Yu gave a talk on “Computational design of interleukin-2 mimetics” and Dr. Wang spoke about “Protein structure determination from cryoEM density maps”. We wish them the best of the luck in their next steps!

The annual RosettaCON meeting was held July 29-Aug1 at the beautiful Sleeping Lady Mountain Resort in Leavenworth, WA. Many IPD scientists attended the conference, heard talks from researchers in Rosetta labs across the country, presented posters on their own research, and socialized with the larger Rosetta community.
