Gene Variant Descriptions | PTEN Y138L lies within the phosphatase tensin-type domain of the Pten protein (UniProt.org). Y138L demonstrates Pten protein stability similar to wild-type protein in one study (PMID: 32366478) and reduced protein stability in another study (PMID: 32350270), and retains lipid phosphatase activity, however, demonstrates loss of protein phosphatase activity (PMID: 22413754), fails to rescue spheroid formation (PMID: 32366478), and fails to suppress Akt phosphorylation in cell culture, and delays development in flies (PMID: 32350270). |
