For survival reasons or otherwise, the immune system would save a "file" of certain intruders and threats based on traits and characteristics. The protein, called Lck, is what "teaches" T-cells (white blood cells that attack viruses and other threats) to identify the characteristics of pathogens, whether clearly or vaguely identified within the body. As a result, Lck helps prevent the body's immune system from being constantly weighed down by a "biological hard drive" remembering all cell and invader statuses.
