Abstract:
Sef (similar expression to fgf genes) was identified as a feedback antagonist of FGF signaling in zerbrafish, mouse and human. Sefhas been reported to function in different ways, however the regulation of Sef stability remains unknown. The possible role of c-Cbl in the regulation of Sef protein degradation was investigated. Results from coimmunoprecipitation and immunostaining assays reveal that hSef colocalizes and interacts with c-Cbl. Data suggest that the interaction between hSef and c-Cbl results in the ubiquitination and subsequent degradation of the hSef protein. It was proposed that c-Cbl may serve as a modulator to regulate Sef protein stability during FGF signal transduction.
