Matr3 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
MATR3 (Matrin 3) is a nuclear matrix protein encoded by the MATR3 gene, located on chromosome 5q31.2[1]. It is a member of the matrin family of RNA-binding proteins and plays diverse roles in nuclear architecture, RNA processing, and gene expression regulation[2]. MATR3 is ubiquitously expressed with high levels in muscle and neuronal tissues.
