title: Cloning of a novel human ELF-1-related ETS transcription factor, ELFR, its characterization and chromosomal assignment relative to ELF-1.
abstract: The ETS gene family encodes a group of proteins that function as transcription factors under physiological conditions and, if aberrantly expressed, can lead to cellular transformation. ETS transcription factors are characterized by a unique conserved DNA binding domain. A subset of these proteins is rearranged with EWS in Ewing tumors (ET). We recently described a spectrum of ETS genes coexpressed with EWS-FLI1 in an ETcell line to define proteins that potentially compete in target site selection. We now report on the cloning and characterization of a novel ETS family member, ELFR, displaying 92% homology to ELF-1 in its DNA binding domain while diverging in the rest of the protein. ELFR expression was found in a very tissue restricted pattern with the highest abundancy in placenta. We also report the chromosomal assignment of ELFR and ELF-1 to Xq26 and 13q13, respectively, by means of fluorescence in-situ hybridization (FISH).
