title: Ubiquitination of α-integrin cytoplasmic tails.
abstract: Recent findings have shown that ubiquitination is involved in regulating several proteins required for cell adhesion and migration. We showed that α5 integrin is ubiquitinated at its cytoplasmic lysines in response to fibronectin binding, and that this is required for its sorting to lysosomes together with fibronectin. Here we speculate whether other α integrin tails may also be ubiquitinated, and discuss the significance of ubiquitin linkages in the regulation of cell adhesion and migration.
