Tropomyosin and troponin are called regulatory proteins because they act like a switch to determine when the fiber can contract and when it cannot.

What is difference between a structural gene and a nonstructural gene?

The difference between a structural gene and a nonstructural gene can be explained that structural gene is a gene encoding the amino acid sequence of a protein. Non-regulatory gene. A structural gene is a gene that codes for any RNA or protein product other than a regulatory element (i.e. regulatory protein)and then it makes proteins in the cell. However, the nonstructural gene is different from structure gene, for example (nonstructural gene)NS1 Influenza Protein is created by the internal protein encoding, linear negative-sense, single stranded RNA, NS gene segment; which found in Influenzavirus A, Influenzavirus B and Influenzavirus C;
