B-lymphoid tyrosine kinase-mediated FAM83A phosphorylation elevates pancreatic tumorigenesis through interacting with β-catenin.

Abstract in brief

• The study finds that FAM83A, a protein previously linked to various cancers, directly interacts with β-catenin, disrupting a complex that usually leads to the degradation of β-catenin, which is important in pancreatic cancer malignancy.!*
• FAM83A is phosphorylated by BLK kinase at a specific site, enhancing its ability to promote Wnt/β-catenin signaling, which contributes to tumor growth by facilitating β-catenin's interaction with TCF4 and preventing certain inhibitors from functioning.!*
• Targeting the interaction between FAM83A and β-catenin using specific peptides shows promise in significantly reducing pancreatic cancer progression in laboratory studies, suggesting a potential new treatment
