Description

Mecp2 is in many mammals an important regulator of neuronal function and development. Mutations impairing the proper function of Mecp2 are mainly associated with the Rett syndrome but may also contribute to other neurological disorders like schizophrenia, FASD, and PPM-X-syndrome. Dependant on the cofactors Mecp2 acts as an activator or repressor of transcription and micro RNA production. It influences RNA splicing and regulates chromatin structure together with HP1 and interferes in methylation of DNA (epigenetics). The expression of Mecp2 itself is highly regulated by promotor elements, cis-regulatory elements, polyadenylation, promotor DNA methylation and miRNA. The pathway is demonstrated for mouse but as the genes are highly conserved in mammals, many of these are valid for human, too.
