Another critical task of proteins exemplifies that old phrase “turnabout is fair play.” Proteins are constructed through gene activity and — in the form of hormones, growth factors, and other regulatory molecules — proteins also affect gene activity. The adjective that describes this phenomenon is e ...

... For a pair of human and bacterium proteins, we predict they can interact if both of them have known interacting orthologs in either E. coli, C. jejuni, H. pylori, S. cerevisae, C. elegans or D. melanogaster. In addition, if a bacterial protein has an ortholog encoded by the human genome, we predict ...

Polycomb Group Proteins and Cancer

The Polycomb-group proteins (PcGs) are a family of proteins that use epigenetic mechanisms to maintain or repress expression of their target genes. They were originally discovered in Drosophila (fruit flies), though they've been shown to be conserved in many species due to their vital roles in embryonic development. These proteins' ability to alter gene expression has made them targets of investigation for research groups seeking to understand disease pathology and oncology.
