What is the official name of the MESP2 gene?
The official name of this gene is “mesoderm posterior bHLH transcription factor 2.”
MESP2 is the gene's official symbol. The MESP2 gene is also known by other names, listed below.

What is the normal function of the MESP2 gene?
The MESP2 gene provides instructions for making a transcription factor, which is a protein that attaches (binds) to specific regions of DNA and helps control the activity of particular genes. The MESP2 protein controls the activity of genes in the Notch pathway, an important pathway in embryonic development. The Notch pathway plays a critical role in the development of vertebrae. Specifically, the MESP2 protein and the Notch pathway are involved in separating future vertebrae from one another during early development, a complex process called somite segmentation. Although the exact mechanism of somite segmentation is unclear, it appears to require the activity of several proteins in the Notch pathway, including the NOTCH1 protein and the MESP2 protein, to be turned on and off in a specific pattern (oscillate).
The MESP2 protein regulates Notch activity by turning on (activating) genes in the Notch pathway, which ultimately block (repress) the activity of the NOTCH1 protein. Additionally, through unknown mechanisms, the MESP2 protein seems to mark the boundary separating future vertebrae from one another.
Does the MESP2 gene share characteristics with other genes?
The MESP2 gene belongs to a family of genes called bHLH (basic helix-loop-helix).
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.
