Summary

Automatic Translation

Målrettet protein degradering representerer en viktig reguleringsmekanisme for cellefunksjon. Det skjer via en konservert Ubiquitin-proteasom, som festes polyubiquitin kjedene til målet protein som deretter tjene som molekylære "koder" for 26S proteasomet. Her beskrives en enkel og pålitelig cellefritt assay for proteasomal degradering av proteiner.
