NCIt definition : The human SPI1 wild-type allele is located in the vicinity of 11p11.2 and is approximately
24 kb in length. This allele, which encodes transcription factor PU.1 protein, is
involved in the activation of transcription by RNA polymerase II.;
NCIt note : The product of the SPI1 gene binds to the PU-box, a purine-rich DNA sequence (5'-
GAGGAA-3') that can act as a lymphoid-specific enhancer of transcription (GeneCards).;
