  • Description: Over 600 E3 ligases have been identified in mammals and most are part of the RING family of E3 ligases. The monomeric family of CBL RING E3 ligases (c-CBL, CBL-B and CBL-C) attenuate nonreceptor and receptor tyrosine kinase signalling through ubiquitination and direct the receptor tyrosine kinases for degradation through the endocytic or proteasomal pathways. Members of the CBL family share a highly conserved N terminus comprising of a tyrosine kinase binding domain, a linker helix region and a RING domain. The more variable C terminus possessing a proline-rich region and a string of terminal amino acids or 'extension'. Mutations in this gene have been implicated in several human cancers including acute myeloid leukaemia. The protein CBL is a ubiquitously expressed 982 amino acid E3 ubiquitin-protein ligase involved in cell signalling and protein ubiquitination.
