CBP1 is a yeast nuclear gene encoding a mitochondrial protein that stabilizes the 5' end of cytochrome b (cob) pre-mRNA. Cytochrome b is the only mitochondrially synthesized component of the respiratory chain complex III. Since the nuclearly encoded subunits of this complex are regulated at the transcriptional level by catabolite repression, we hypothesized that CBP1 might be similarly regulated. To test the idea that transcriptional regulation of CBP1 could coordinate an increase in cytochrome b mRNA stability with an increase in nuclearly encoded complex III subunit production, we characterized the change in abundance of CBP1 mRNA during derepression on a nonfermentable carbon source. Poly(A)+ RNA from derepressed yeast cells was examined by Northern (RNA) analyses with cRNA probes from CBP1. Both 2.2- and 1.3-kilobase (kb) transcripts were detected. The 1.3-kb mRNA lacked approximately 900 nucleotides of the 3' end of the 2.2-kb mRNA, which encodes the carboxyl-terminal 250 amino acid residues of the CBP1 coding sequence. Northern analyses of RNA isolated from deletion-insertion mutants of CBP1 and from strains that overexpress CBP1 mRNA demonstrated that both mRNAs were transcribed from the CBP1 gene. Furthermore, we demonstrated that the levels of the two CBP1 mRNAs were reciprocally regulated by the carbon source in the growth medium. This is the first description of a yeast gene from which two transcripts that can encode proteins with distinctly different coding properties are generated by alternative 3'-end formation.

Species Specific

Muscle-DNA from cattle and buffalo was extracted to amplify the mitochondrial DNA segment (cytochrome b gene) and the gene encoding species-specific repeat (SSR) region. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and SSR techniques were used to identify of species origin. Restriction analysis of PCR-RFLP of the mitochondrial cytochrome b segment and SSR analysis showed no differences between cattle and buffalo. Where, the fragment length (bp) generated by AluI PCR-RFLP were 190, 169 and PCR amplification size of the gene encoding SSR region was 603 bp in both cattle and buffalo. Consequently, finding from this study could be revealed that cattle and buffalo are evolutionary derived from the same ancestor.

Phylogenetic analysis of two species of snake Eryx colubrinus loveridgei and Ptyas mucosus was investigated using the gene encoding cytochrome b. The nucleotide sequences of complete and partial mtDNA cytochrome b were determined in numerous specimens. Sequence divergence between species and genera was evenly distributed in the cytochrome b gene but rather high compared to reports for other fish species. Phylogenetic analyses on complete cytochrome b were used to study the relationships among the considered species. The molecular phylogeny of sample was determined by analyzing cytochrome b gene sequences. On the basis of position of sequence of the given python sample in the phylogenetic tree, the sample showed closest similarity with Eryx colubrinus loveridgei and Ptyas mucosus.
