چکیده

cDNA for rat alpha-lactalbumin has been cloned in bacterial plasmid, and its sequence has been analyzed. The DNA sequence analysis shows that rat alpha-lactalbumin has 17 extra residues beyond the COOH terminus of the alpha-lactalbumin isolated and sequenced to date from other species. The predicted COOH-terminal sequence is hydrophobic and proline rich and bears some resemblance to beta-casein sequences.

Comparison of the nucleotide sequence of cloned human and guinea-pig pre-alpha-lactalbumin cDNA with that of chick pre-lysozyme cDNA suggests evolution from a common ancestral gene.

Nucleotide sequence analyses of essentially full-length copies of human and guinea-pig pre-alpha-lactalbumin cDNAs contained within recombinant plasmids, (i) confirm the presence of 19 amino acid hydrophobic amino terminal peptide extensions encoded within each mRNA; and (ii) provides evidence for the existence of a minor variant of guinea-pig alpha-lactalbumin mRNA encoding a protein with a 36...

Cloning and sequencing of rat plectin indicates a 466-kD polypeptide chain with a three-domain structure based on a central alpha-helical coiled coil

We have determined the complete cDNA sequence of rat plectin from a number of well-characterized overlapping lambda gt11 clones. The 4,140-residue predicted amino acid sequence (466,481 D) is consistent with a three-domain structural model in which a long central rod domain, having mainly an alpha-helical coiled coil conformation, is flanked by globular NH2- and COOH-terminal domains. The plect...

Nucleotide and predicted amino acid sequences of cloned human and mouse preprocathepsin B cDNAs.

Cathepsin B is a lysosomal thiol proteinase that may have additional extralysosomal functions. To further our investigations on the structure, mode of biosynthesis, and intracellular sorting of this enzyme, we have determined the complete coding sequences for human and mouse preprocathepsin B by using cDNA clones isolated from human hepatoma and kidney phage libraries. The nucleotide sequences ...

Molecular cloning of cDNA for human prothymosin alpha.

A cDNA library was constructed from human spleen mRNA and screened for clones containing cDNAs coding for prothymosin alpha. A clone containing a 503-base-pair insert including the entire coding sequence for the translated portion of the mRNA was isolated. The deduced amino acid sequence confirms and completes the partial sequence of human prothymosin alpha determined by protein sequencing meth...
