    Abstract

    c-CBL (CBL) encodes a multifunctional protein engaged in the regulation of intracellular signaling pathways. It was first identified as a cellular counterpart of the viral oncogene, v-CBL, that causes murine lymphoma. Although no genetic evidence existed suggesting its role in human carcinogenesis, the recent discovery of c-CBL mutations in myeloid cancers has unveiled a unique oncogenic mechanism mediated by gain-of-function of a mutated tumor suppressor, closely associated with allelic conversion of 11q arms. In this review, we summarize our current knowledge about c-CBL mutations and discuss the molecular mechanisms of their gain-of-function.
