Protein Effect | loss of function |
Gene Variant Descriptions | CBL K382E lies within the RING-type zinc finger domain of the Cbl protein (UniProt.org). K382E confers a loss of function to Cbl as demonstrated by lack of Cbl activity (PMID: 26676746), impaired internalization, ubiquitination, and degradation of Egfr, and decreased inhibition of Erk1/2 phosphorylation in culture (PMID: 25178484). |
