DefinitionThis section has been translated automatically.

The EDA gene (EDA stands for "ectodysplasin A") is a protein-coding gene located on chromosome Xq13.1. Several transcript variants have been found for this gene, encoding many different ectodysplasin isoforms. Isoform 1 binds only to the receptor EDAR, whereas isoform 3 binds exclusively to the receptor EDA2R.

General informationThis section has been translated automatically.

Ectodysplasin A is a type II membrane protein that can be cleaved by furin to form a secreted form. The protein belongs to the tumor necrosis factor family and acts as a homotrimer. It may be involved in cell-cell signaling during ectodermal organ development. Ectodysplasin A further functions as a ligand that activates the DEATH domain-containing receptors EDAR and EDA2R. possibly the protein also plays a role in cell adhesion.

Defects in the EDA gene are associated with.
