Cbl‑b
Cbl‑b is a single‑chain RING finger ubiquitin ligase that acts as a master regulator of immune activation. By ubiquitinating key signalling molecules in T‑cells, B‑cells and NK cells, Cbl‑b maintains immune tolerance and prevents hyperactivation. Loss of Cbl‑b leads to autoimmunity and enhanced anti‑tumour immunity, making it a critical player in immune homeostasis and a promising target in cancer immunotherapy.
CBL Family Ubiquitin Ligase
The CBL family of ubiquitin ligases—c‑Cbl, Cbl‑b and Cbl‑c—are single‑chain RING finger E3 enzymes that regulate receptor tyrosine kinase signalling, immune activation and epithelial homeostasis. Through their TKB and RING domains, CBL proteins control ubiquitination, endocytosis and signal attenuation. Dysregulation of CBL ligases contributes to cancer, autoimmunity and inflammatory disorders, highlighting their importance in cellular regulation and disease.
