Background: PU.1/Spi-1
Spi1 (SFFV proviral integration 1 protein; also PU.1 and Sfpi1) is a 37-41 kDa member of the ets family of transcription factors. It is both an RNA and DNA binding protein that is found in hematopoietic cells such as B cells, neutrophils, macrophages and dendritic cells (DC). Spi1 can act as both a transcriptional activator and repressor. In DC, Spi1 promotes the expression of CD80, CD86 and CD11b, while in proerythroblasts, it blocks GATA-1 induced transcriptional activation. Spi1 binds to DNA as a monomer, and interacts with multiple factors such as Runx-1, IRF8, GATA-1 and c-Jun. Mouse Spi1 is 272 amino acids (aa) in length. It contains a transactivation region (aa 7-117), a PEST domain (aa 118-164), and a DNA-binding domain (aa 165-266). Phosphorylation on Ser41, 142 and 148 increases activity. There is one alternative start site at Met7. Over aa 1-169, mouse Spi1 shares 88% and 81% aa identity with rat and human Spi1, respectively.
