Biologists Glean Insight into Repetitive Protein Sequences

By September 16, 2022No Comments

About 70 percent of all human proteins include at least one sequence consisting of a single amino acid repeated many times, with a few other amino acids sprinkled in. These “low-complexity regions” are also found in most other organisms.

The proteins that contain these sequences have many different functions, but MIT biologists have now come up with a way to identify and study them as a unified group. Their technique allows them to analyze similarities and differences between LCRs from different species, and helps them to determine the functions of these sequences and the proteins in which they are found.
