MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes an ETS-domain transcription factor that activates gene expression during myeloid and B-lymphoid cell development. The nuclear protein binds to a purine-rich sequence known as the PU-box found near the promoters of target genes, and regulates their expression in coordination with other transcription factors and cofactors. The protein can also regulate alternative splicing of target genes. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
PHENOTYPE: Nullizygous mice may exhibit fetal or perinatal lethality, absence of myeloid and B cells, and altered T cell and NK cell development. Mice carrying hypomorphic alleles display impaired B-cell and myeloid development, develop T cell derived lymphomas andacute myeloid leukemia, and die prematurely. [provided by MGI curators]
