L-Myc is a protein that plays a crucial role in regulating cell growth and division. It is part of the Myc family of transcription factors, which are essential for controlling the expression of genes involved in cell proliferation and metabolism. L-Myc is particularly important in certain types of cancer, where its overexpression can lead to uncontrolled cell growth. L-Myc is primarily expressed in the developing nervous system and in some tissues like the lungs. Research has shown that it can interact with other proteins and pathways, influencing various cellular processes. Understanding L-Myc's function may provide insights into potential cancer therapies targeting Myc family proteins.
