Gene | APC |
Variant | Q1338* |
Impact List | nonsense |
Protein Effect | loss of function |
Gene Variant Descriptions | APC Q1338* results in a premature truncation of the Apc protein at amino acid 1338 of 2843 (UniProt.org). Q1338* retains binding with Axin1 but confers a loss of function to Apc as demonstrated by decreased beta-catenin recruitment, phosphorylation, and ubiquitination in cultured cells (PMID: 34352208). |
