FAT atypical cadherin 1 (FAT1) protein is encoded by a gene mapped to human chromosome 4q34-35. The protein has ubiquitous expression in mammalian tissues, especially higher in kidney glomerular epithelial cells. FAT1 is localized to the leading edge of lamellipodia, filopodia, and microspike tips of cells. The protein is found to be abnormally expressed in pediatric patients with acute leukemia.The encoded protein is characterized with cytoplasmic domain that is involved in assembly of components necessary to promote ectopic actin polymerization.

Biochem Physiol Actions: FAT atypical cadherin 1 (FAT1) acts as a proximal element of cell migration signaling pathways.FAT1 interacts with Ena/Vasodilator-stimulated phosphoprotein (VASP) at the leading edges of lamellipodia, filopodia, and microspike tips and helps in normal actin dynamics and cell polarization. FAT1, with or without ß-catenin, might function as a novel biomarker for breast cancer. Mutation of FAT1 gene leads to T-cell acute lymphoblastic leukemia (T-ALL) in adults. In humans, FAT1 might act both as an oncogene and a tumor suppressor. The protein modulates oncogenic pathways in glioma cell lines. FAT1 also act as a co-activator of hypoxia and growth receptor signaling to critical tumorigenic pathways in hepatocellular carcinoma (HCC).
