Characterization of murine cytomegalovirus m157 from infected cells and identification of critical residues mediating recognition by the NK cell receptor Ly49H.

Activated NK cells mediate potent cytolytic and secretory effector functions and are vital components of the early antiviral immune response. NK cell activities are regulated by the assortment of inhibitory receptors that recognize MHC class I ligands expressed on healthy cells and activating receptors that recognize inducible host ligands or ligands that are not well characterized. The activating Ly49H receptor of mouse NK cells is unique in that it specifically recognizes a virally encoded ligand, the m157 glycoprotein of murine CMV (MCMV).

1274 full-open reading frames of transcripts expressed in the developing mouse nervous system.

As part of the trans-National Institutes of Health (NIH) Mouse Brain Molecular Anatomy Project (BMAP), and in close coordination with the NIH Mammalian Gene Collection Program (MGC), we initiated a large-scale project to clone, identify, and sequence the complete open reading frame (ORF) of transcripts expressed in the developing mouse nervous system. Here we report the analysis of the ORF sequence of 1274 cDNAs, obtained from 47 full-length-enriched cDNA libraries, constructed by using a novel approach, herein described. cDNA libraries were derived from size-fractionated cytoplasmic mRNA isolated from brain and eye tissues obtained at several embryonic stages and postnatal days.
