Yes, but only to some degree. Not all dietary protein you eat goes toward protein synthesis. Once you eat enough protein to drive protein synthesis, your body will oxidize protein for energy. Driving your protein intake far beyond the realm of 30-35 percent of your daily calories probably won’t provide additional muscle-building benefits, but it will cut into your fat and carbohydrate intake, which may actually hinder your goals. This isn’t exact, but eating at least 1 gram of protein per pound per day should cover your bases.
