We previously identified a B-cell-specific regulatory element in the immunoglobulin heavy chain (IgH) enhancer, pi, with striking similarity to binding sites for ets-related transcription factors. Whereas the ability of ets-related factors to bind to and transactivate the pi site has been substantiated, the identification of the particular member of the ets family responsible for B-cell-specific regulation of the pi site has remained controversial. We have used antibodies specific for individual members of the ets family to evaluate which ets-related factor in B-cell nuclear extracts interacts with the IgH pi site. We present strong evidence that ELF-1 is highly expressed in B-cells and is one of two major factors specifically interacting with the murine IgH enhancer pi site in B-cell nuclear extracts. Binding of ELF-1 correlates with activity of the pi site, since mutations abolishing function of pi also inhibit binding of ELF-1. Furthermore, we demonstrate that ELF-1 can transactivate the IgH enhancer in HeLa cells, suggesting a role for ELF-1 in B-cell-specific IgH gene expression.
