Nuclease Mapping

We determined the DNA sequence and mapped the corresponding transcripts of a genomic clone containing the Gmhsp26-A gene of soybean. This gene is homologous to the previously characterized cDNA clone pCE54 (E. Czarnecka, L. Edelman, F. Schöffl, and J. L. Key, Plant Mol. Biol. 3:45-58, 1984) and is expressed in response to a wide variety of physiological stresses including heat shock (HS). S1 nuclease mapping of transcripts and a comparison of the cDNA sequence with the genomic sequence indicated the presence of a soybean seedlings with either CdCl2 or CuSO4. Analysis of the 5' termini of transcripts indicated the presence of one major and at least two minor start sites. In each case, initiation occurred 27 to 30 base pairs downstream from a TATA-like motif, and thus each initiation site appears to be promoted by the activity of a separate subpromoter. The three subpromoters are all associated with sequences showing low homology to the HS consensus element of Drosophila melanogaster HS genes and are differentially induced in response to various stresses. Within the carboxyl-terminal half of the protein, hydropathy analysis of the deduced amino acid sequence indicated a high degree of relatedness to the small HS proteins. A comparison of the primary amino acid sequence of hsp26-A with sequences of the small HS proteins suggested that this stress protein is highly diverged and may therefore be specialized for stress adaptation in soybean.

Abstract Platelet aggregation requires the binding of adhesive proteins such as fibrinogen to the heterodimer of membrane glycoproteins IIb (GPIIb) and IIIa (GPIIIa). Human erythroleukemia (HEL) cells synthesize both GPIIb and GPIIIa. Using poly(A+) RNA purified from HEL cells, we constructed a cDNA library in the lambda gt10 phage vector. This library was screened with a 38mer oligonucleotide derived from a platelet GPIIIa peptide, and three overlapping cDNAs were isolated. The three inserts encompassed 3.5 kilobases (kb), including the entire coding region of mature GPIIIa (2,286 basepairs, bp) and 1.3 kb of 3′ untranslated sequence. All 222 residues determined directly from platelet GPIIIa tryptic peptides exactly matched the HEL cell-deduced amino acid sequence. The HEL cell sequence matched a previously reported endothelial cell cDNA sequence except for eight nucleotides. Five of these nucleotide differences were silent changes consistent with genetic polymorphisms. The other three differences resulted in changes in the deduced amino acid sequence of GPIIIa; reexamination of the endothelial cell cDNA sequence in these three areas revealed that it is actually identical to the HEL cell sequence. The virtual identity of the endothelial and HEL cell cDNA sequences provides direct evidence that GPIIIa is a subunit common to cell-adhesion receptors present in more than one cell type. We localized the gene for GPIIIa to chromosome 17, the same chromosome to which we had previously mapped the gene for GPIIb.

By using synthetic oligonucleotides as probes, plasmid clones containing portions of cDNA coding for human C4b-binding protein were isolated from a liver cDNA library. The entire amino acid sequence of the C4b-binding protein can be predicted from this study of the cloned cDNA when allied to a previous sequence study at the protein level [Chung, Gagnon & Reid (1985) Mol. Immunol. 22, 427-435], in which over 55% of the amino acid sequence, including the N-terminal 62 residues, was obtained. The plasmid clones isolated allowed the unambiguous determination of 1717 nucleotides of cDNA sequence between the codon for the 32nd amino acid in the sequence of C4b-binding protein and the 164th nucleotide in the 3′ non-translated region. The sequence studies show that the secreted form of C4b-binding protein, found in plasma, is composed of chains of apparent Mr 70 000 that contains 549 amino acid residues. Examination of the protein and cDNA sequence results show that there are at least two polymorphic sites in the molecule. One is at position 44, which can be glutamine or threonine, and the other is at position 309, which can be tyrosine or histidine. Northern-blot analysis indicated that the mRNA for C4b-binding protein is approx. 2.5 kilobases long. The N-terminal 491 amino acids of C4b-binding protein can be divided into eight internal homologous regions, each approx. 60 amino acids long, which can be aligned by the presence in each region of four half-cystine, one tryptophan and several other conserved residues. These regions in C4b-binding protein are homologous with the three internal-homology regions that have been reported to be present within the Ba region of the complement enzyme factor B and also to the internal-homology regions found in the non-complement beta 2-glycoprotein I.
