Electric Industries obtains United States patent.Electric Industries, Ltd. (Osaka, Japan) has patented a novel protein having a high degree of homology to the amino acid amino acid (əmē`nō), any one of a class of simple organic compounds containing carbon, hydrogen, oxygen, nitrogen, and in certain cases sulfur. These compounds are the building blocks of proteins. sequence of the so-called cyclin cy·clin n. A class of proteins that fluctuate in concentration at specific points during the cell cycle and that regulate the cycle by binding to a kinase. box which is characteristic of cyclins cyclins a set of related proteins that regulate the passage of cells through the cell cycle by forming complexes with cyclin-dependent protein kinases. cyclins-dependent protein kinase (Cdk) : they are herein referred to as "human cyclin I" or "human cyclin I protein." Further, the invention relates to a gene encoding their amino acid sequences and the protein: the gene is referred to as "gene encoding human cyclin I" or "human cyclin I gene." Also, the invention relates to expression vector expression vector n. A vector, such as a plasmid, yeast, or animal virus genome, used to introduce foreign genetic material into a host cell in order to replicate and amplify the foreign DNA sequences as a recombinant molecule. into which the human cyclin I gene is incorporated as well as to a transformant into which the vector is introduced. Still further, the invention relates to a recombinant protein obtained by growing the transformant. In addition, the invention relates to a novel neuron-marking method using an anitisense nucleotide of the gene as probe. Furthermore, the invention relates to method for screening cancer cell using the human cyclin I gene. (US 7,001,985) |
