FRAT1 and FRAT2 genes, clustered in human chromosome 10q24, are human homologues to mouse proto-oncogene Frat1, which promotes carcinogenesis through activation of the WNT - beta-catenin - TCF signaling pathway.
Modulation of FRAT2 leads to concomitant changes in Rac activity, and transformation of Frat knockout hematopoietic progenitor cells by MLL fusions results in leukemias displaying reduced Rac activation and increased sensitivity to chemotherapeutic drugs.
