Gene | CBL |
Variant | Y371del |
Impact List | deletion |
Protein Effect | loss of function |
Gene Variant Descriptions | CBL Y371del results in the deletion of one amino acid in the linker region of the Cbl protein at amino acid 371 (UniProt.org). Y371del confers a loss of function to the Cbl protein as indicated by failure to regulate phosphorylation, demonstrating increased phosphorylation of intracellular proteins in cell culture (PMID: 9671395), decreased apoptosis, increased cell cycle progression, and transformation of cultured cells in the presence of FLT3 (PMID: 20622007, PMID: 31943762). |
