Transcription factor LBX1 is a protein that in humans is encoded by the LBX1 gene.^[5]^[6]

This gene and the orthologous mouse gene were found by their homology to the Drosophila lady bird early and late homeobox genes.

In the mouse, this gene is a key regulator of muscle precursor cell migration and is required for the acquisition of dorsal identities of forelimb muscles.^[6]
