The Cbl family of proteins act as E3 ubiquitin-protein ligases and have been associated with the down regulation of a variety of receptor tyrosine kinases. Cbl proteins associate with many different cell signalling molecules suggesting that they may have functions outside of the RING finger-mediated ubiquitin ligase activity. The Drosophila melanogaster cbl gene (D-cbl) encodes two splice forms (Oncogene 19 (2000) 3299). Here we report on the differential expression of these isoforms during Drosophila embryogenesis. Both isoforms are maternally expressed but the long isoform of D-cbl is also transiently expressed in the invaginating mesoderm and later is specifically expressed in neurons of the central nervous system (CNS). Cbl protein is shown to be localised to axons of the longitudinal connectives and commissures in the central nervous system.
