CRYSTAL STRUCTURE OF A SOLUBLE FORM OF THE HUMAN T CELL CO-RECEPTOR CD8 AT 2.6 ANGSTROMS RESOLUTIONCRYSTAL STRUCTURE OF A SOLUBLE FORM OF THE HUMAN T CELL CO-RECEPTOR CD8 AT 2.6 ANGSTROMS RESOLUTION
Structural highlights
Disease[CD8A_HUMAN] Defects in CD8A are a cause of familial CD8 deficiency (CD8 deficiency) [MIM:608957]. Familial CD8 deficiency is a novel autosomal recessive immunologic defect characterized by absence of CD8+ cells, leading to recurrent bacterial infections. Function[CD8A_HUMAN] Identifies cytotoxic/suppressor T-cells that interact with MHC class I bearing targets. CD8 is thought to play a role in the process of T-cell mediated killing. CD8 alpha chains binds to class I MHC molecules alpha-3 domains. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedA 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. Crystal structure of a soluble form of the human T cell coreceptor CD8 at 2.6 A resolution.,Leahy DJ, Axel R, Hendrickson WA Cell. 1992 Mar 20;68(6):1145-62. PMID:1547508[1] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. See AlsoReferences |
