Mouse urinary protein (MUP), molecular model. MUP refers to a family of similar proteins found in mouse urine. The proteins act as pheromones, airborne chemical signals, and trigger various responses in other mice, such as aggression between male mice. This model shows the protein's secondary structure of beta sheets and alpha helices.
