Drosophila Protein
Product of Cytogene CG 14732
This piece is based on a protein of unknown function encoded in the Drosophila genome. The sequence of the Drosophila genome was reported in 2000 (Science Mar 24 2000: 2185-2195), but many of the protein coding genes have unknown functions.
If the function of the protein is unknown, how do we know that anything is encoded by this region? Protein coding genes are characterized by "open reading frames". Open reading frames are stretches of DNA that begin with a start signal, end with a stop signal, and contain a continuously translatable sequences in between. Cytogene CG14732 is located in the right arm of Drosophila chromosome 3. The entire translatable 874-amino acid sequence of the open reading frame appears in the box below. Since the function of the protein has not been identified, and its folding structure has not been analyzed, no features of the protein are indicated.

Notes on the Music:
This piece plays both the sequence of the protein and that of its encoding DNA. The DNA is played throughout by percussion instruments that beat out the DNA sequence in sets of three notes -- the triplet codons of the DNA. The protein is played by English horn, and is embellished periodically by human voices singing the protein sequence at a slower tempo.
This music was composed using BankStep sequencing software from Algorithmic Arts, and was created specifically for a genetics student who did a research project on a Drosophila mystery protein.
