Music Used to Identify Proteins

            Music for me is something that plays a huge role in my life. I’m always listening, playing, or singing some kind of music. So when I saw this new study it definitely peaked my interest. Structures of proteins can now be studied in a completely new and different way, by listening to music. This technique is theorized to more easily help scientists identify anomalies in proteins.

            By using a process called sonification, the data about the proteins can be turned into musical sounds and melodies. This approach is being used to ask three questions: what can protein data sound like? Are there any analytical benefits to this? In this data can specific elements or anomalies be heard? This technique can be used to help recognize fold structures of proteins by each protein sequence having a melodic shape. The amino acid sequences correlate to musical notes, with their properties being reflected by sound qualities.

            38 people were selected for the test to decide how well the sonification of the three proteins; 1ny9, 1r75, and 1div.pdb, were perceived in relation to data sources. From the 38 people, most of them were students, with 21 of them having more than one year of musical training, 17 having up to or more than one year of protein study, and 10 with no training in either. The subjects were giving four answer choices to choose from in their comparison of the sonifications to visual components: A) similar, B) not similar, C) sometimes similar, D) mostly similar. There were a total of six experiments, with the first two used to establish both positive (similar) and negative (not similar) controls. The results from the experiments showed that a good majority of the subjects were able to discern the correlations between the data related images and sounds. The study is hoping to expand to a more complete fold identification system to identify 3D folds of different proteins. Sonification is also being done on DNA sequences and gene expressions.

  1. We did our blog on the same topic! lol! But I found this topic really interesting, which is why I wrote about it, but I am really intrigued and I actually would really like to listen to the melodies that these proteins produce!

  2. Music impacts society every day. It's so interesting that music created by sonification can be used to provide information about protein structures that could not be determined from other means. The potential for sonifications to detect genetic disease markers puts a whole new meaning to the phrase "music can heal you".
