Human c-myb protooncogene: nucleotide sequence of cDNA and organization of the genomic locus. 1986

B Majello, and L C Kenyon, and R Dalla-Favera

We have isolated cDNA clones of the human c-myb mRNA that contain approximately 3.4 kilobases of the approximately 3.8-kilobase mRNA sequence. Nucleotide sequence analysis shows that the c-myb mRNA contains an open reading frame of 1920 nucleotides, which could encode a 72-kDa protein. The cDNA nucleotide sequence and the predicted amino acid sequence of the c-myb protein are highly homologous to the corresponding chicken and mouse proteins. In particular, a region toward the NH2 terminus of the protein containing a 3-fold tandem repeat of 51 residues is evolutionarily conserved and is the only region of homology with the Drosophila c-myb protein. This region may represent a functionally important structure, most likely the DNA-binding domain. cDNA clones have been used to isolate genomic clones and to define a preliminary intron/exon organization of the c-myb gene. Identification of 5' and 3' coding and noncoding exons indicates that the human c-myb locus spans a 40-kilobase region.

D011518 Proto-Oncogene Proteins Products of proto-oncogenes. Normally they do not have oncogenic or transforming properties, but are involved in the regulation or differentiation of cell growth. They often have protein kinase activity.

D011519 Proto-Oncogenes Normal cellular genes homologous to viral oncogenes. The products of proto-oncogenes are important regulators of biological processes and appear to be involved in the events that serve to maintain the ordered procession through the cell cycle. Proto-oncogenes have names of the form c-onc. Proto-Oncogene,Proto Oncogene,Proto Oncogenes
D002896 Chromosomes, Human, Pair 6 A specific pair GROUP C CHROMSOMES of the human chromosome classification. Chromosome 6
D003001 Cloning, Molecular The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells. Molecular Cloning
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
