Die Länge spezifischer Ubiquitin-ketten beeinflusst ihre Erkennung

The attachment of differently linked ubiquitin (Ub) chains of varying length to proteins is a prevalent posttranslational modification in eukaryotic cells. We established an affinity enrichment approach for the identification of linkage- and length-selective ubiquitin binding proteins and could show that in addition to the linkage, the length of a Ub chain is an important determinant for Ub chain recognition.
