For example, the TEL1/ETV6 (TEL1) gene is required for normal yolk sac angiogenesis, adult bone marrow hematopoiesis, and is rearranged or deleted in numerous leukemias.     ///    "Identification and characterization of a new human ETS-family transcription factor, TEL2, that is expressed in hematopoietic tissues and can associate with TEL1/ETV6.. "    ///    DNA binding assays show that TEL2 can bind the same consensus DNA binding sequence recognized by TEL1/ETV6.
