Hi! My name is Detective Myosin and I am on an mission. I have been hired by Mr. Bicep muscle to find Actin and work with him to help Mr. Bicep contract, but first let me tell you a little about myself.

This is what I look like!

I am a fibrous protein from Sacromere, that forms with an actin to help in the process of muscle contraction. I'm pretty good at my job, however, there is this one guy named Tropomyosin who is constantly getting in my way. He is the protein that decides if a muscle can contract or not.
