Rae-1 delta: Products

The Rae-1 proteins, including Rae-1 alpha, beta, gamma, delta, and epsilon, are members of a family of GPI-linked proteins that function as ligands for mouse NKG2D. The Rae-1 proteins are distantly related to MHC class I proteins, but they possess only the alpha 1 and alpha 2 Ig-like domains, and they have no ability to bind peptide or interact with beta 2-microglobulin. The genes encoding these proteins are not found within the Major Histocompatibility Complex on mouse chromosome 17, but rather map to mouse chromosome 10. Rae-1 family members have retinoic acid-inducible elements in their promoter regions.
