Clone: G146-222

Description: Fli-1 is a 50 kDa ets-related transcription factor. Like other ets-related proteins it binds to consensus sites in DNA through an 85 amino acid ets domain in the carboxyl region of the protein. Fli-1 is associated with Ewing sarcoma (EWS) through a t(11,22)(q24,q12) chromosomal translocation. This translocation brings the 5' region of the EWS gene into conjunction with the 3' region of the Fli-1 gene encoding the ets-DNA binding domain. Such a translocation is found in 85% of Ewing sarcomas. The resulting fusion protein has the DNA binding activity of Fli- 1 and, with the EWS domain, it is also a more potent transcriptional activator than Fli-1 itself. The strong transforming activity of the EWS-Fli-1 fusion protein may in part be due to its ability to transactivate the promoter for c-myc. G146-222 recognizes human Fli-1. The antibody was raised against a bacterially expressed Fli-1 ets domain fusion protein.

Characteristics: 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
