Abstract Successful cellular immunotherapy for cancer utilising cytotoxic T lymphocytes (CTL) requires efficient expansion while maintaining effector function. Understanding how CTL expansion and function are regulated during the cell preparation process is thus important. Here, we show that T cell-specific deletion of Prmt7 using CD4-Cre increases CD8+ T cell effector differentiation, cytokine secretion, cytolytic activity and anti-tumor responses.

Abstract The ubiquitin system regulates virtually all cellular processes, yet the vast majority of ubiquitylation sites identified in the human proteome cannot be attributed to specific E3 ligases. This knowledge gap hampers our understanding of ubiquitin signaling and the development of therapeutics leveraging the ubiquitylation system.

Abstract Here we describe ProtacID, a flexible BioID (proximity-dependent biotinylation)-based approach to identify PROTAC-proximal proteins in living cells.
