What is the official name of the LMX1B gene?
The official name of this gene is “LIM homeobox transcription factor 1, beta.”
LMX1B is the gene's official symbol. The LMX1B gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the LMX1B gene?
The LMX1B gene provides instructions for producing a protein that attaches (binds) to specific regions of DNA and regulates the activity of other genes. On the basis of this role, the LMX1B protein is called a transcription factor. The LMX1B protein appears to be particularly important during early embryonic development of the limbs, kidneys, and eyes.
Does the LMX1B gene share characteristics with other genes?
The LMX1B gene belongs to a family of genes called homeobox (homeoboxes).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
