LIM domain-binding protein 1 (LDB1)

Binds to the LIM domain of a huge variety of LIM domain- containing transcription factors. May regulate the transcriptional activity of LIM-containing proteins by determining specific partner interactions.

Plays a role in the growth of interneurons and motor neurons in cooperation with LHX3 and ISL1. Acts synergistically with LHX1/LIM1 in axis formation and activation of gene expression.
