Flow cytometric analysis of Daudi cells with CBL (phospho Tyr774) monoclonal antibody, clone R3B8 (FITC)(Cat # MAB23377). Untreated as negative control (blue) or untreated (red) or treated with IFNα + IL-4 + pervanadate (green)
The cbl oncogene was first identified as part of a transforming retrovirus which induces mouse pre-B and pro-B cell lymphomas. As an adaptor protein for receptor protein-tyrosine kinases, it positively regulates receptor protein-tyrosine kinase ubiquitination in a manner dependent upon its variant SH2 and RING finger domains. Ubiquitination of receptor protein-tyrosine kinases terminates signaling by marking active receptors for degradation. [provided by RefSeq
