FLI1
Friend leukemia integration 1 transcription factor(FLI1), also known astranscription factor ERGB,is aproteinthat in humans is encoded by theFLI1gene,which is aproto-oncogene.[5][6][7]
Function[edit]
Fli-1 is a member of theETS transcription factor familythat was first identified inerythroleukemiasinduced by Friend Murine Leukemia Virus (F-MuLV). Fli-1 is activated throughretroviralinsertional mutagenesisin 90% of F-MuLV-induced erythroleukemias. The constitutive activation of fli-1 inerythroblastsleads to a dramatic shift in theEpo/Epo-Rsignal transduction pathway, blocking erythroid differentiation, activating theRaspathway, 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.[citation needed]
Clinical significance[edit]
In addition to Friend erythroleukemia, proviral integration at the fli-1 locus also occurs in leukemias induced by the 10A1, Graffi, and Cas-Br-E viruses. Fli-1 aberrant expression is also associated with chromosomal abnormalities in humans. In pediatricEwing’s sarcomaa chromosomal translocation generates a fusion of the 5’ transactivation domain ofEWSR1(also known as EWS) with the 3’ Ets domain of Fli-1. The resulting fusion oncoprotein, EWS/Fli-1, acts as an aberrant transcriptional activator.[8]with strong transforming capabilities. EWS/Fli-1 may steer clinically important genes via interaction withenhancer-like GGAA-microsatellites.[9]The importance of Fli-1 in the development of human leukemia, such as acute myelogenous leukemia (AML), has been demonstrated in studies of translocation involving theTeltranscription factor, which interacts with Fli-1 through protein-protein interactions. A recent study has demonstrated high levels of Fli-1 expression in several benign and malignant neoplasms using immunohistochemistry.[citation needed]
A possible association withParis-Trousseau syndromehas been suggested.[10]
