* Information From OMIM

Function: D'Sa-Eipper et al. (1996) showed that the BFL1 protein suppresses apoptosis induced by the p53 tumor suppressor protein in a manner similar to other BCL2 family members. The BFL1 gene showed a dominant cooperating oncogenic activity with the E1A oncogene in transformation of primary rodent epithelial cells.
