Abstract
N6-methyladenosine (m6A) is a dynamic RNA modification that regulates various aspects of RNA metabolism and has been implicated in many biological processes and transitions. m6A is highly abundant in the brain; however, only recently has the role of m6A in brain development been a focus. The machinery that controls m6A is critically important for proper neurodevelopment, and the precise mechanisms by which m6A regulates these processes are starting to emerge. However, the role of m6A in neurodegenerative and neuropsychiatric diseases still requires much elucidation. This review discusses and summarizes the current body of knowledge surrounding the function of the m6A modification in regulating normal brain development, neurodegenerative diseases and outlines possible future directions.
