Recent Advances in Top‐Down Proteomics for Single‐Cell Research
ABSTRACT Individual cells have distinctive molecular characteristics, including biologically relevant proteoforms. Although single‐cell (SC) molecular omics offer unprecedented insights into cellular heterogeneity and function, the characterization of proteoforms in SCs remains an uncharted territory.

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Proteoforms in Disease: Biomedical Applications of Top‐Down Proteomics
ABSTRACT The proteome is a dynamic landscape of proteoforms arising from genetic mutations, alternative splicing, and post‐translational modifications (PTMs), which collectively drive biological function and disease phenotypes. Mass spectrometry (MS)‐based proteomics has emerged as an essential technique for elucidating this molecular complexity ...

Protein Glutamylation: From Cytoskeleton to Signaling
Tubulin glutamylation, γ‐glutamylation, and nontubulin glutamylation are distinct yet interconnected post‐translational modifications that regulate diverse physiological and pathological processes, including cytoskeletal organization, cell cycle progression, immunity, metabolism, and disease development.

Molecular Glue Degraders in Early Development for Cancer Therapy
ABSTRACT Molecular glue degraders are an emerging class of small molecule allosteric modulators that induce or stabilize protein‐protein interactions, enabling targeted degradation of previously intractable proteins. By redirecting E3 ligases to recognize neosubstrates, proteins that are not typically recognized by a specific E3 ubiquitin ligase, they ...
