Sequence Motifs and their Biological Significance

Sequence motifs are nucleic acid sequences that are widespread across or within a genomes and have or are speculated to have certain regulatory or structural biological functions.

Motifs that are found in different parts of the genomes like exons, introns and junk, have different functions. Motifs present in the exons ( coding part of the genome) decide the structure of the protein or label proteins to be sent to certain parts of the cell for processes like phosphorylation. Motifs that are present in introns (which makes up the non coding part of genome) are usually the regulatory sequences which determine the amount of gene expression and binding sites of proteins. Satellite DNA, which is the main component of centromeres and heterochromatin, is an example of motif found in junk parts of the genome.
