What is the normal function of the SBF2 gene?
The SBF2 gene (also called MTMR13) provides instructions for making a protein called SET binding factor 2. The function of this protein is unknown, but it is probably involved in the development of specialized cells in the nervous system called Schwann cells. Schwann cells produce myelin, the protective substance that covers nerve cells and promotes the rapid transmission of nerve impulses. SET binding factor 2 probably also plays a role in the development of mesh-like canals (trabecular meshwork) that surround the colored part of the eye (the iris). The trabecular meshwork helps drain excess fluid from the eye.
Does the SBF2 gene share characteristics with other genes?
The SBF2 gene belongs to a family of genes called PTP (protein tyrosine phosphatases).
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.
