Ectodysplasin A (EDA) is a protein that in humans is encoded by the EDA gene.
Ectodysplasin A is a transmembrane protein of the TNF family which plays an important role in the development of ectodermal tissues such as skin in humans.[5][6] It is recognized by the ectodysplasin A receptor.
Function
[edit]The protein encoded by this gene is a type II membrane protein that can be cleaved by furin to produce a secreted form. The encoded protein, which belongs to the tumor necrosis factor family, acts as a homotrimer and may be involved in cell-cell signaling during the development of ectodermal organs. Along with c-Met, it has been shown to be involved in the differentiation of anatomical placodes, precursors of scales, feathers and hair follicles in vertebrates.[7] Defects in this gene are a cause of ectodermal dysplasia, anhidrotic, which is also known as X-linked hypohidrotic ectodermal dysplasia. Several transcript variants encoding many different isoforms have been found for this gene.[6] At least 61 disease-causing mutations in this gene have been discovered.[8]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
