Anti-EDA1 Antibody

Ectodysplasin A (EDA1) is a member of the TNF-related ligand family involved in the early epithelial-mesenchymal interaction that regulates ectodermal appendage formation (1) . It is a trimeric type II membrane protein that co-localizes with cytoskeletal structures at the lateral and apical surfaces of cells and can be expressed as eight alternatively spliced isoforms in hair follicles and in the epidermis of adult skin (2,3) . EDAs are required during development, and loss or mutation of EDA1 results in a group of developmental disorders identified as ectodermal dysplasia type 1 (4,5) .

EDA1 antibody was raised against an 19 amino acid peptide near the center of human EDA1. The immunogen is located within amino acids 130 - 180 of EDA1.

Not abundant; expressed in specific cell types of ectodermal (but not mesodermal) origin of keratinocytes, hair follicles, sweat glands. Also in adult heart, liver, muscle, pancreas, prostate, fetal liver, uterus, small intestine and umbilical chord.

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:8696334, PubMed:11039935, PubMed:27144394) . May also play a role in cell adhesion (By similarity) .
