No that is a misconception. not all proteins are going to build our body muscle. Muscular proteins such as actin, myosin are the major part of our body muscle that contract for our movement. In addition fibrinogen and fibrins are are involved in blood clotting process.
Houses do not have proteins and do not have muscles.

Muscle proteins are used to stimulate the growth of an exerted muscle. Even when the muscle isn't exerted it needs protein to repair and recover from the exertion previous but without exertion the muscle can no longer grow and will deplete This also applies when exerting a muscle with no protein intake (or very little). The muscle can no longer grow because the muscle has used all the stored muscle proteins for previous growth, as above once the original proteins are gone they must be replaced for extra or maintained mass.
