Variant | P428L |
Impact List | missense |
Protein Effect | no effect - predicted |
Gene Variant Descriptions | CBL P428L lies within the region of the Cbl protein required for ubiquitination of SPRED2 (UniProt.org). P428L demonstrates ubiquitin ligase activity similar to wild-type Cbl towards Egfr in culture (PMID: 26676746), and therefore, is predicted to have no effect on Cbl protein function. |
