Proteoform medicine: characterizing and targeting protein forms in human disease
Nature Reviews Genetics, Published online: 05 January 2026; doi:10.1038/s41576-025-00915-1Proteoforms are the diverse protein molecules produced from a single gene whose primary sequence and composition can be diversified by genetic, transcriptomic, translational and post-translational variation. This Review synthesizes technologies and network approaches to map, quantify and functionally characterize proteoforms, outlining routes to proteoform-guided biomarkers and therapeutics

I have to comment here. The idea is interesting, the results compelling, but choose your models wisely. An APOE4 on a P301S background is just an unfeasible bomb. If you want to show that APOE4 carries pathology independently, you put it on regular hTau knock in. www.biorxiv.org/content/10.1...
