CRYSTAL STRUCTURE OF A SOLUBLE FORM OF THE HUMAN T CELL CO-RECEPTOR CD8 AT 2.6 ANGSTROMS RESOLUTION
Contents |
Overview
A secreted fragment of the extracellular portion of human CD8 alpha has, been expressed in CHO cells, and a deglycosylated and proteolyzed form of, this fragment has been crystallized. We report here the crystal structure, of this fragment as refined at 2.6 A resolution. The structure was solved, by molecular replacement using a superposition of ten variable domains, from immunoglobulin light chains as the search model. Only the N-terminal, 114 amino acids of CD8 alpha are visible in the electron density maps. The, domain formed by these residues possesses a fold typical of immunoglobulin, variable domains and associates to form Fv-like homodimers.
Disease
Known disease associated with this structure: Megakaryoblastic leukemia, acute OMIM:[606078]
