Construction of chimeric plasmids containing histone H5 cDNA from hen erythrocyte. DNA sequence of a fragment derived from the 5' region of H5 mRNA.
We report that construction and characterization of chicken erythrocyte histone H5 cDNA recombinant plasmids. cDNA was synthesized from poly(A)+ polysomal RNA enriched in H5 mRNA and inserted into the PstI site of pBR322. Several clones containing H5 cDNA sequences were obtained and one of them (p541), expressing H5 antigenic determinants, was sequenced. The DNA insert of p541 contains 118 nucl...
متن کاملMapping of histone H5 sites on nucleosomes using immunoelectron microscopy.
The location of histone H5 on nucleosomes has been determined by binding anti-H5 antibodies to dinucleosomes, and recording the position of the bound IgG molecules using electron microscopy. Two types of antibody were employed, a total IgG fraction prepared from rabbits immunized with H5/RNA, which reacted to all three domains (NH2-terminal, central globular, and COOH-terminal) of H5, and an im...
متن کاملOpposite replication polarities of transcribed and nontranscribed histone H5 genes.
We used an in vitro nuclear runoff replication assay to analyze the direction of replication of the active and inactive histone H5 genes in avian cells. In embryonic erythrocytes the transcribed histone H5 gene displayed sensitivity to endogenous nuclease cleavage. In contrast, this gene was insensitive to endogenous nuclease digestion under the same conditions in nuclei of the lymphoblastoid c...
متن کاملEnhanced human receptor binding by H5 haemagglutinins
Mutant H5N1 influenza viruses have been isolated from humans that have increased human receptor avidity. We have compared the receptor binding properties of these mutants with those of wild-type viruses, and determined the structures of their haemagglutinins in complex with receptor analogues. Mutants from Vietnam bind tighter to human receptor by acquiring basic residues near the receptor bind...
متن کاملBasal expression of the histone H5 gene is controlled by positive and negative cis-acting sequences.
Sequences from -3500 to +1365 of the chicken histone H5 gene have been analyzed for the presence of cis-acting elements in H5 expressing (transformed CFU-E) and non-expressing cells (fibroblasts). The region from -3500 to -115 had little effect on transcription. Proximal upstream sequences contain a negative element (UNE, -115 to -95), capable to also repress the activity of the heterologous HS...
