Cblc belongs to a family of ubiquitin protein ligases (E3s) that negatively regulate signaling by targeting activated tyrosine kinases for degradation. Cblc is the most recently cloned member of the Cbl proteins and is expressed only in epithelial cells (the other Cbl proteins are ubiquitous). Cblc, like the other mammalian Cbl proteins, can ubiquitinate the activated EGFR and target it for degradation. Cblc knock out mice show no obvious phenotype. Thus, the physiological role of Cblc is not known.
