Pyknon
A pyknon is a new type of putative regulatory motif that named from the greek adjective for dense. By definition, pyknons are variable length sequences with a statistically significant number of intact copies in the intergenic and intronic regions of the genome and additional copies in the untranslated or amino acid coding regions of known transcripts. Even though the original presentation discussed pyknons in the context of the human genome, pyknons likely represent a more general architectural component of eukaryotic genomes. The exact role of pyknons is currently unclear but the findings so far support a regulatory responsibility. The possibility has been raised that pyknons hint at a previously unseen layer of cell process regulation.
