The function of Ensembl gene identifier ENSG00000158813 (EDA, ectodysplasin A) is as follows. Cytokine which is involved in epithelial-mesenchymal signaling during morphogenesis of ectodermal organs. Functions as a ligand activating the DEATH-domain containing receptors EDAR and EDA2R (PubMed:11039935, PubMed:27144394, PubMed:34582123, PubMed:8696334). May also play a role in cell adhesion (By similarity). {ECO:0000250|UniProtKB:O54693, ECO:0000269|PubMed:11039935, ECO:0000269|PubMed:27144394, ECO:0000269|PubMed:34582123, ECO:0000269|PubMed:8696334}. [Isoform 1]: Binds only to the receptor EDAR, while isoform 3 binds exclusively to the receptor EDA2R. {ECO:0000269|PubMed:11039935, ECO:0000269|PubMed:27144394}. [Isoform 3]: Binds only to the receptor EDA2R. .
