The Carboxyl-terminal End of Cox1 Is Required for Feedback Assembly Regulation of Cox1 Synthesis in Saccharomyces cerevisiae Mitochondria [PDF]
Journal of Biological Chemistry, 2010 Synthesis of the largest cytochrome c oxidase (CcO) subunit, Cox1, on yeast mitochondrial ribosomes is coupled to assembly of CcO. The translational activator Mss51 is sequestered in early assembly intermediate complexes by an interaction with Cox14 that depends on the presence of newly synthesized Cox1. If CcO assembly is prevented, the level of Mss51

Cyclooxygenase 1 (COX1) as an indicator of sperm quality in humans
Andrologia, 2020Sperm quality is important for in vitro fertilisation and embryo transfer and intracytoplasmic sperm injection in the treatment of human infertility. The purpose of this study was to screen for biomarkers that could evaluate sperm quality. We analysed semen samples in 172 fertile males; multivariate logistic regression analysis showed that the levels ...

A Novel Function of Pet54 in Regulation of Cox1 Synthesis in Saccharomyces cerevisiae Mitochondria [PDF]
Journal of Biological Chemistry, 2016 Cytochrome c oxidase assembly requires the synthesis of the mitochondria-encoded core subunits, Cox1, Cox2, and Cox3. In yeast, Pet54 protein is required to activate translation of the COX3 mRNA and to process the aI5β intron on the COX1 transcript. Here we report a third, novel function of Pet54 on Cox1 synthesis.

An inverted repeat in the mitochondrial DNA of carrot mitochondrial type (mitotype) SW3 has been sequenced in the context of its up- and downstream genomic environments. The 3,159 bp repeat encodes rps7 and cox1, but the cox1 reading frame does not encode a stop codon at a position predicted by alignment with other plant cox1 genes; cox1 extends into ...

Motive representation in nucleotide densities of bird's mitochondrial gene COX1
Proceedings of the 4th International Symposium on Applied Sciences in Biomedical and Communication Technologies, 2011Estimated number of species is 7--100 million of prokaryotes and eukaryotes. Just a small fraction has been identified up to the present days. Morphological taxonomy is not able to process such huge diversity. Methods based on analysis of DNA sequences can be much more successful.

Horizontal Gene Transfer has Impacted cox1 Gene Evolution in Cassytha filiformis
Journal of Molecular Evolution, 2020The gene cox1 is one of the most reported mitochondrial genes involved in horizontal gene transfer among angiosperms. However, whether different cox1 copies exist in different populations of a species and whether any other novel way except intron homing exists for cox1 intron acquisition is less understood.

New mechanism for COX1 in ovarian cancer
The Lancet Oncology, 2005364 http://oncology.thelancet.com Vol 6 June 2005 Cyclooxygenase 1 (COX1), but not COX2, is highly expressed in epithelial ovarian cancers in humans and in mice, according to new research (Cancer Res 2005; 65: 3735–44). “Our work appears to be very important since the question regarding the relative role of COX1 and COX2 [in tumour formation] remains ...

Mitochondrial DNA, 2009
The translation initiation codon of the mitochondrial (mt) cytochrome oxidase I gene, cox1, frequently differs from conventional AUN triplets, and the termination codon is often incomplete.To investigate whether initiation and termination codon usage may depend on the rate of mt genome evolution, a fast evolving locus comprising cox1 and adjacent tRNA ...

The MSS51 gene product is required for the translation of the COX1 mRNA in yeast mitochondria
Molecular and General Genetics MGG, 1990The MSS51 gene product has been previously shown to be involved in the splicing of the mitochondrial pre-mRNA of cytochrome oxidase subunit I (COX1). We show here that it is specifically required for the translation of the COX1 mRNA. Furthermore, the paromocyin-resistance mutation (P454R) which affects the 15S mitoribosomal RNA, interferes, directly or

Deficiency of cox1 gene expression in wheat plants with Aegilops columnaris cytoplasm
Current Genetics, 1996Wheat plants with Aegilops columnaris cytoplasm are characterized by growth inhibition and partial male sterility and show an impaired mitochondrial cytochrome c oxidase activity. We designed this study to clarify the functional relationship between this impaired cytochrome c oxidase activity and possible structural alterations to the mitochondrial ...
