Abstract

The RBTN2 LIM-domain protein, originally identified as an oncogenic protein in human T-cell leukemia, is essential for erythropoiesis. A possible role for RBTN2 in transcription during erythropoiesis has been investigated. Direct interaction of the RBTN2 protein was observed in vivo and in vitro with the GATA1 or -2 zinc-finger transcription factors, as well as with the basic helix-loop-helix protein TAL1. By using mammalian two-hybrid analysis, complexes involving RBTN2, TAL1, and GATA1, together with E47, the basic helix-loop-helix heterodimerization partner of TAL1, could be demonstrated. Thus, a molecular link exists between three proteins crucial for erythropoiesis, and the data suggest that variations in amounts of complexes involving RBTN2, TAL1, and GATA1 could be important for erythroid differentiation.
