Danre Lmo2 Antibody / Rhombotin 2, 100 ug

Lmo2, or LIM domain only protein two, is a transcriptional regulator that plays a critical role in hematopoietic and vascular development. In zebrafish, Lmo2 is essential for the specification of blood and endothelial lineages and is widely used as a molecular marker for early hematopoietic progenitor cells.

Lmo2 does not directly bind to DNA but functions as a scaffold protein, forming complexes with other transcription factors to regulate gene expression. During zebrafish embryogenesis, Lmo2 is expressed in the intermediate cell mass, the site of primitive blood cell formation, and in the developing vasculature. It is required for the emergence of both erythroid and myeloid lineages, as well as for the proper development of endothelial cells.

Loss of Lmo2 function in zebrafish results in severe defects in blood cell formation and vascular patterning, highlighting its central role in mesodermal differentiation. Because of its strong evolutionary conservation and defined expression patterns, zebrafish Lmo2 serves as a powerful model for studying hematopoiesis, angiogenesis, and transcriptional networks involved in early development.

Lmo2 is also relevant to human health, as misregulation of Lmo2 has been associated with leukemia. This makes zebrafish Lmo2 a valuable tool in both basic research and disease modeling related to blood development and cancer biology.
