| Source/Purification | Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala86 of human Spi-B protein. |
| Background | Spi-B belongs to the ETS family of transcription factors and activates transcription through direct binding to the PU box (1). Spi-B was identified based on its homology with PU.1/Spi-I (1). The function of Spi-B is most well studied in B cells and plasmacytoid dendritic cells (pDCs). B cells from mice deficient in Spi-B proliferate poorly and die in response to signaling through the B cell receptor (2). In addition, Spi-B(-/-) mice have a defect in germinal center formation (2). Spi-B plays a role in both the development and function of pDCs. It is highly expressed by pDCs and not by monocyte-derived DCs, and overexpression of Spi-B in hematopoietic progenitor cells inhibits development of other lymphoid lineages (3). pDCs from Spi-B(-/-) mice produce less interferon in response to TLR7 and TLR9 stimulation and have lower expression of pDC-specific surface markers (4). Finally, Spi-B is required for differentiation of intestinal microfold cells (5,6). |
