    Notes: [Auszug] Computational methods were used to predict the sequences of peptides that bind to the MHC class I molecule, Kb. The rules for predicting binding sequences, which are limited, are based on preferences for certain amino acids in certain positions of the peptide. It is apparent though, that binding ...

    Notes: Abstract CENP-B is a centromere associated protein originally identified in human cells as an 80 kDa autoantigen recognized by sera from patients with anti-centromere antibodies (ACA). Recent evidence indicates that CENP-B interacts with centromeric heterochromatin in human chromosomes and may bind to a specific subset of human alphoid satellite DNA. CENP-B has not been unambiguously identified in non-primates and could, in principal, be a primate-specific alphoid DNA binding protein. In this work, a human genomic DNA segment containing the CENP-B gene was isolated and subjected to DNA sequence analysis. In vitro expression identified the site for translation initiation of CENP-B, demonstrating that it is encoded by an intronless open reading frame (ORF) in human DNA. A homologous mouse gene was also isolated and characterized. It was found to possess a high degree of homology with the human gene, containing an intronless ORF coding for a 599 residue polypeptide with 96% sequence similarity to human CENP-B. 5′ and 3′ flanking and untranslated sequences were conserved at a level of 94.6% and 82.7%, respectively, suggesting that the regulatory properties of CENP-B may be conserved as well. CENP-B mRNA was detected in mouse cells and tissues and an immunoreactive nuclear protein identical in size to human CENP-B was detected in mouse 3T3 cells using human ACA. Analysis of the sequence of CENP-B revealed a segment of significant similarity to a DNA binding motif identified for the helix-loop-helix (HLH) family of DNA binding proteins. These data demonstrate that CENP-B is a highly conserved mammalian protein that may be a member of the HLH protein family and suggest that it plays a role in a conserved aspect of centromere structure or function.

    Notes: Abstract We have determined the nucleotide sequence of two small circular DNA plasmids, pCf1 and pCf2 [22], from the marine diatom Cylindrotheca fusiformis. pCf1 is 4273 bp, and pCf2 is 4079 bp in size. In each plasmid, all of the major open reading frames (ORFs) are encoded on the same DNA strand. Two ORFs are similar, comparing the two plasmids. ORF218 (pCf1) and ORF217 (pCf2) share 80% amino acid identity and ORF482 (pCf1) and ORF484 (pCf2) share 54% amino acid identity. ORF218/217 shows significant similarity (28–31% amino acid identity) to the Tn3 class of resolvases. Resolvases are most commonly found in bacterial transposons. However, two other features found in the Tn3 class of transposon are missing in the plasmids; an ORF encoding a transposase and terminal inverted repeat sequences. This, and data mapping the portions of the plasmids that hybridize to genomic chloroplast DNA, suggest that the plasmids do not contain active transposons. By analogy with the R46 plasmid from Enterobacter [5, 6], another potential role for the resolvases encoded by pCf1 and pCf2 is the conversion of multimeric forms of the plasmid to monomers. The similarity of ORF218/217 to resolvases documents the first identification of a potential coding function in an algal plasmid.
