The nuclear matrix has remained a contentious structure for decades; many believe that it is an artefact of harsh non-physiological procedures. However, its visualization using milder experimental techniques is leading to its general acceptance by the scientific community. It is a permanent network of core filaments underlying thicker fibres which is proposed to be a platform for numerous important nuclear activities such as transcription and DNA repair. Interestingly, A- and B-type lamin proteins and emerin are components of this nuclear structure; however, they are often referred to only as nuclear envelope proteins. The present mini-review intends to provide an overview of the nuclear matrix, mentioning both its constituents and functional significance. The impact of disease-causing mutations in both emerin and lamin proteins on the structure's ability to regulate and mediate nuclear processes is then discussed.
