ProteinWege

ProteinWege is a conceptual framework used in protein biology and nutrition to describe the sequential and interconnected pathways by which proteins are produced, processed, trafficked, and degraded within a cell. The name combines protein with Wege, a term meaning paths, signaling a systems-level view of proteostasis rather than a single linear process.

Core concepts within ProteinWege include translation and co-translational folding, aided by molecular chaperones; post-translational modifications that alter activity or localization; intracellular trafficking and compartmentalization; functional localization and interaction networks; and regulated proteolysis that governs protein turnover. Quality-control mechanisms, such as the proteostasis network, are central to maintaining proper folding and limiting aggregation.

Analytically, ProteinWege relies on network modeling, kinetic data, and multi-omics information to map how perturbations—genetic, environmental, or pharmacological—affect the life cycle of proteins. Computational tools, quantitative proteomics, and imaging assays are commonly used to infer pathway relationships, measure flux through different routes, and predict system-wide responses to stress or intervention.

Applications of ProteinWege span basic research, disease understanding, and biotechnology. In research, the framework helps study diseases linked to misfolding, improper trafficking, or altered degradation. In biotechnology and drug development, it supports identification of targets that modulate proteostasis or protein quality control. In nutrition science, it offers a lens to evaluate protein quality and digestibility by considering how dietary proteins are processed through digestive and cellular pathways.

ProteinWege is intended as a flexible, non-prescriptive perspective that complements established concepts like the proteostasis network and systems biology, enabling integrated analyses of protein life cycles across organisms and contexts.
