“…44 As a RF ubiquitin ligase, the biological significance of CBLB enzymatic activity is a rapidly evolving area of research, with the discovery of its role in immunomodulation of the innate immune system published in 2014. 7,8,[45][46][47][48][49] This research activity highlights the need for small-molecule modulators of CBLB activity that can be used to better understand both the biology of this target in a research setting as well as those that can be translated into a clinical setting to improve disease outcomes. The experiments described in this article are the first published cell-free screen for modulators of CBLB enzymatic activity.…”
