Only in mammals?
At the start of the article we can read "Alpha-keratin, or α-keratin, is a type of keratin found in mammals." But it seems that the epidermal appendages of reptiles and birds are characterized by the presence of both alpha (α) and beta (β) type keratin proteins.--Furado (talk) 20:23, 24 July 2018 (UTC)
