Flow cytometric analysis of Daudi NE with CBL (phospho Y774) monoclonal antibody, clone R3B8 (FITC) (Cat # MAB23489). 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
