Mammalian evolution of human cis-regulatory elements and transcription factor binding sites
Science, 2023Understanding the regulatory landscape of the human genome is a long-standing objective of modern biology. Using the reference-free alignment across 241 mammalian genomes produced by the Zoonomia Consortium, we charted evolutionary trajectories for 0.92 ...

STEM CELLS, 1993
Erythroid differentiation leads to the production of red blood cells that contain a high level of hemoglobin. This level is mainly regulated by globin gene transcription during development and differentiation. Although numerous cis-acting sequences are involved in transcriptional activity of globin genes, combinations of three motifs, CCACC, SP1 and ...

Regulatory elements in the KlHEM1 promoter
Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2008In Kluyveromyces lactis the gene encoding 5-aminolevulinate synthase, KlHEM1, is regulated at the transcriptional level by carbon source and oxygen availability. The KlHEM1 promoter, fused to the reporter lacZ gene, has been analysed by deletion and direct mutagenesis techniques in order to find regulatory elements functionally relevant in this ...

Regulatory elements in aflatoxin biosynthesis
Mycotoxin Research, 2006This review provides a synopsis of factors involved in the regulation of aflatoxin inAspergillus species at the molecular level. Much of the knowledge available today on the regulation of secondary metabolite production in fungi has been gleaned from studies of the aflatoxin gene cluster inA. flavus andA.

REGULATORY ELEMENTS OF MARINE CYANOBACTERIA
Genome Informatics 2007, 2007The free-living, oxyphototroph bacteria of the group of Prochlorococcus populate widely the oceans. Genomic information of nine marine cyanobacteria was used to predict signals essential for regulation. We implemented a pipeline that automatically calculates BLASTp alignments of query genomes, selects a representative subset of orthologs and predicts ...

Prediction of Regulatory Elements
2008Finding the regulatory mechanisms responsible for gene expression remains one of the most important challenges for biomedical research. A major focus in cellular biology is to find functional transcription factor binding sites (TFBS) responsible for the regulation of a downstream gene.

Structures of regulatory elements in mRNAs
Current Opinion in Structural Biology, 2006Messenger RNAs often contain structures in their 5'-untranslated region that serve to regulate or promote expression of their gene product. Recent structural studies have revealed that riboswitches, which bind a variety of small molecule metabolites, including purine bases, S-adenosylmethionine, amino acids and cofactors, can contain sophisticated ...
