Systematic name M7526
Brief description Genes down-regulated in double positive thymocytes stimulated by anti-CD3: ELK4 [GeneID=2005] knockout versus ELK1 and ELK4 [GeneID=2002;2005] knockout.
Full description or abstract Removal of the transcription factor SAP1a member of the Ternary Complex Factor (TCF) group of transcription factors which in conjunction with Serum Response Factor (SRF) has been shown to have a profound effect on positive selection in the thymus. When another TCF Elk1 is knocked out in mice there is no effect on positive selection unless it is on a Sap1a KO background where the phenotype is very severe. We have stimulated isolated double positive T cells (DPs) with anti-CD3 to mimic positive selection and compared basal and stimulated transcription across the four genotypes to discover the downstream targets of Sap1a involved in positive selection.
