How rhomboid proteins help cells remove misfolded membrane proteins

The Discovery of Molecules and Mechanisms of the Rhomboid Superfamily

NIH-funded research University of California, San Diego · NIH-11266200

The lab will study how rhomboid-family proteins pull out and clear faulty membrane proteins, which could matter for people with Alzheimer's and similar conditions.

What this research studies

Researchers will use yeast and cell-based experiments to map how a protein called Dfm1 and related rhomboid proteins move misfolded membrane proteins out of the endoplasmic reticulum for destruction. They will combine genetic screens, biochemistry, and cell biology to define the step-by-step retrotranslocation mechanism, examine a stress state caused by aggregated membrane proteins, and explore links to sphingolipid metabolism. The work is done in the laboratory and focuses on basic molecular mechanisms rather than testing treatments in people. Results could point to molecular targets for future therapies but will not involve patient treatment during this project.

Who could benefit from this research

Good fit: This project does not enroll patients — it is lab-based using yeast and cell models, so there are no participant eligibility criteria.

Not a fit: People seeking immediate treatments or clinical care for Alzheimer's will not receive direct benefit from this preclinical laboratory research.

Why it matters

Potential benefit: If successful, this work could reveal new molecular targets to help cells clear toxic misfolded proteins, potentially informing future Alzheimer's treatments.

How similar studies have performed: Prior basic studies in yeast and cells have shown rhomboid/derlin proteins affect protein removal and ER stress, but applying these findings to human Alzheimer's therapy remains largely unproven.
