Protein Information
Name CBL
Synonyms CBL2, RNF55
Function 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, SRC and other kinases of the SRC family and mediates their ubiquitination and degradation. Participates in signal transduction in hematopoietic cells. Plays an important role in the regulation of osteoblast differentiation and apoptosis. Essential for osteoclastic bone resorption. The 'Tyr-731' phosphorylated form induces the activation and recruitment of phosphatidylinositol 3-kinase to the cell membrane in a signaling pathway that is critical for osteoclast function. May be functionally coupled with the E2 ubiquitin-protein ligase UB2D3.
Cellular Location Cytoplasm. Cell membrane. Note=Colocalizes with FGFR2 in lipid rafts at the cell membrane

c-Cbl, product of c-cbl proto-oncogene, is a 120 kDa cytoplasmic protein involved in tyrosine kinase-dependent signaling pathways (1-3). c-Cbl is one of the earliest targets of tyrosine phosphorylation in response to a number of cellular stimuli. For instance, stimulation of growth factor receptors by EGF, PDGF, NGF and FGF, results in c-Cbl tyrosine phosphorylation, in lymphoid and other cell lines (4).
