Product Description | Recombinant Human MICA Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains Glu24-Gln308. |
Product Background |
MICA (MHC class I chain-related gene A) is a transmembrane glycoprotein that functions as a ligand for human NKG2D. A closely related protein, MICB, shares 85% amino acid identity with MICA. These proteins are distantly related to the MHC class I proteins. They possess three extracellular Ig‑like domains, but they have no capacity to bind peptide or interact with beta 2-microglobulin.. |
