N-Myc is a protein that plays a crucial role in cell growth, division, and differentiation. It is part of the Myc family of transcription factors, which help regulate the expression of genes involved in these processes. N-Myc is particularly important during embryonic development and in the functioning of certain tissues, such as the nervous system. In adults, abnormal levels of N-Myc can be associated with various cancers, especially neuroblastoma, a type of cancer that primarily affects children. Research into N-Myc aims to understand its functions better and develop targeted therapies to combat cancers linked to its overexpression.
