CBL (E3 Ubiquitin-protein Ligase CBL, Casitas B-lineage Lymphoma Proto-oncogene, Proto-oncogene c-Cbl, RING Finger Protein 55, Signal Transduction Protein CBL, CBL2, RNF55) (PE)

Adapter protein that functions as a negative regulator of many signaling pathways that are triggered by activation of cell surface receptors. Acts as an E3 ubiquitin-protein ligase, which accepts ubiquitin from specific E2 ubiquitin-conjugating enzymes, and then transfers it to substrates promoting their degradation by the proteasome. Recognizes activated receptor tyrosine kinases, including KIT, FLT1, FGFR1, FGFR2, PDGFRA, PDGFRB, EGFR, CSF1R, EPHA8 and KDR and terminates signaling. Recognizes membrane-bound HCK and other kinases of the SRC family and mediates their ubiquitination and degradation....
