LIM-only protein Lmo2 forms a protein complex with erythroid transcription factor GATA-1.

The LIM-only protein Lmo2, originally identified as an oncogenic protein in human T cell leukemia, is essential for erythropoiesis. A possible role for Lmo2 in transcription during erythropoiesis has been investigated. Direct interaction of Lmo2 was observed in vitro and in vivo with the zinc finger transcription factor GATA-1, as well as with the basic helix-loop-helix (bHLH) transcription factor Tall. By using mammalian two-hybrid analysis, E47/Tall/Lmo2/GATA-1 protein complex could be demonstrated. Thus, a molecular link exists between three proteins crucial for erythropoiesis. This data suggest that variations in amounts of complexes involving Lmo2, Tall, and GATA-1 could be important for erythroid differentiation.[1]
