Biolegend, 658006, Alexa Fluor® 594 anti-SPI1 (PU.1) Antibody, 100μg

SPI1 is a transcription factor belonging to the E26-transformation-specific (Ets) family and is exclusively expressed in hematopoietic cells. SPI1 regulates cell fate decisions during differentiation of hematopoietic stem cells, which is crucial for the development of lymphoid and myeloid cell lineages. SPI1-deficient mice lack macrophages, neutrophils, and B lymphocytes, and they die before or shortly after birth. Abnormally regulated expression of SPI1 can lead to developmental defects as well as occurring malignancy. Overexpression of SPI1 blocks erythroid differentiation and inhibits cell death.  Mice carrying a mutant SPI1 allele show decreased SPI1 expression and develop acute myeloid leukaemia (AML), suggesting the role of SPI1 in oncogenesis.
