Protein spotlight

a question of perspective

Paradigms are meant to be broken. In the 1980s, biology students were taught "the one gene = one protein" dogma which has since stepped down from its pedestal, as we now know that one gene, by way of any number of post-translational modifications on the protein sequence, can actually give rise to more than one protein. Or what would be more correct: to more than one function…
