LMO2 (LIM domain only 2)

Gene

• Entrez ID: 4005
• Gene name: LIM domain only 2
• Gene symbol: LMO2
• Synonyms (NCBI Gene): LMO-2, RBTN2, RBTNL1, RHOM2, TTG2
• Chromosome: 11
• Chromosome location: 11p13
• Summary: 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 approxima
