The c-Cbl proto-oncogene is a ubiquitously expressed cytoplasmic adaptor protein that is especially predominant in hematopoietic cells (1,2).
c-Cbl is rapidly tyrosine-phosphorylated in response to stimulation of a variety of cell-surface receptors and becomes associated with a number of intracellular signaling molecules such as protein tyrosine kinases, phosphatidylinositol-3 kinase, Crk, and 14-3-3 proteins (3,4).
c-Cbl possesses a highly conserved amino-terminal phosphotyrosine binding domain (TKB) and a C3HC4 RING finger motif.
The TKB recognizes phosphorylated tyrosines on activated receptor tyrosine kinases (RTKs) as well as other nonreceptor tyrosine kinases.
The RING finger motif recruits ubiquitin-conjugating enzymes.
These two domains are primarily responsible for the ubiquitin ligase activity of c-Cbl and downregulation of RTKs (3).
Research studies have indicated that in human cancer tissues, c-Cbl is frequently tyrosine-phosphorylated in a tumor-specific manner (5).
Phosphorylation of Tyr731 of c-Cbl provides a docking site for downstream signaling components such as p85 and Fyn (6).
It has been demonstrated that c-Cbl is phosphorylated at Tyr700 by Fyn, Yes, and Syk (4) and that Vav, a hematopoietic-restricted Rac guanine nucleotide exchange factor, undergoes c-Cbl-dependent ubiquitination upon recruitment to phospho-Tyr700 (5).
