Goosecoid: ProductsGoosecoid (GSC) is a 28 kDa member of the paired homeobox family. Human Goosecoid is 257 amino acids (aa) in length, and contains one DNA-binding homeodomain (aa 160 - 219). Goosecoid appearance correlates with the start of gastrulation and the development of both head/neck and upper body limb mesenchyme. It also appears abnormally in some tumors where it is associated with an epithelial-to-mesenchymal transition. Human Goosecoid shares 97% aa sequence identity with mouse Goosecoid.
