Description

EnkiLife provides the Recombinant Human MICA (C-6His) protein,aslo know as MHC Class I Polypeptide-Related Sequence A,MIC-A,MICA,PERB11.1, which features high purity, high activity, and high stability. It can be applied in scientific research, biopharmaceuticals, and other fields.Purity:Greater than 95% as determined by reducing SDS-PAGE;Endotoxin Level:<1 EU/µg as determined by LAL test.;Construction:Recombinant Human MHC Class I Polypeptide-Related Sequence A is produced by our Mammalian expression system and the target gene encoding Glu24-Gln308 is expressed with a 6His tag at the C-terminus.Accession:AAH16929.1. Expression Host:Human Cells.Species:Human.Predicted Molecular Mass:33.87 KDa. Background:MHC Class I Polypeptide-Related Sequence A (MICA) is a transmembrane glycoprotein that functions as a ligand for human NKG2D. Unlike classical MHC class I molecules, MICA does not form a heterodimer with beta-2-microglobulin. MICA shares 85% amino acid identity with a closely related protein, MICB. MICA acts as a stress-induced self-antigen that is recognized by NK cells, NKT cells, and most of the subtypes of T cells. As a Ligand for the KLRK1/NKG2D receptor, MICA binds to KLRK1 leads to cell lysis. MICA functions as an antigen for gamma delta T cells and is frequently expressed in epithelial tumors. MICA antigens are able to elicit the synthesis of alloantibodies in transplant recipients. Studies have shown that anti-MICA antibodies are associated with acute renal allograft rejection and failure. MICA recognition is involved in tumor surveillance, viral infections, and autoimmune diseases.
