Structural highlights
Disease
SPI1_MOUSE Note=Involved in murine acute Friend erythroleukemia. It is a target region for SFFV proviral insertion.
Function
SPI1_MOUSE Binds to the PU-box, a purine-rich DNA sequence (5'-GAGGAA-3') that can act as a lymphoid-specific enhancer. This protein is a transcriptional activator that may be specifically involved in the differentiation or activation of macrophages or B-cells. Also binds RNA and may modulate pre-mRNA splicing.[1]
