MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] LMO2 encodes a cysteine-rich, two LIM-domain protein that is required for yolk sac erythropoiesis. The LMO2 protein has a central and crucial role in hematopoietic development and is highly conserved. The LMO2 transcription start site is located approximately 25 kb downstream from the 11p13 T-cell translocation cluster (11p13 ttc), where a number T-cell acute lymphoblastic leukemia-specific translocations occur. Alternative splicing results in multiple transcript variants encoding different isoforms.[provided by RefSeq, Nov 2008]
PHENOTYPE: Homozygotes for a targeted null mutation exhibit lack of yolk sac erythropoiesis and die around embryonic day 10.5. [provided by MGI curators]
