Anti-FLI1 Antibody Picoband®

Friend leukemia integration 1 transcription factor, also known as Transcription factor ERGB or Proto-oncogene Fli-1 is a protein that in humans is encoded by the human FLI1 gene. The fli1 protooncogene encodes a member of the ETS family of winged helix-turn-helix transcription factors. This gene is mapped to 11q24.3. Fli-1 is activated through retroviral insertional mutagenesis in 90% of F-MuLV-induced erythroleukemias. The constitutive activation of fli-1 in erythroblasts leads to a dramatic shift in the Epo/Epo-R signal transduction pathway, blocking erythroid differentiation, activating the Ras pathway, and resulting in massive Epo-independent proliferation of erythroblasts. These results suggest that Fli-1 overexpression in erythroblasts alters their responsiveness to Epo and triggers abnormal proliferation by switching the signaling event (s) associated with terminal differentiation to proliferation.
