question: Is SATB1 expressed in thymocytes?
answer: A thymocyte factor SATB1 suppresses transcription of stably integrated matrix-attachment region-linked reporter genes. SATB1 is a homeodomain protein and is predominantly expressed in thymocytes. In this study we show that special AT-rich binding protein 1 (SATB1), a T lineage-enriched chromatin organizer and regulator, is induced in response to TCR signaling during early thymocyte development
