Detailed explanation-1: -Nuclear matrix is the network of fibers within the nucleus. It is the cytoskeleton of the nucleus. While the cell contains a cytoskeleton that provides structural support and a means of transport throughout the cytoplasm, the nucleus also contains fibrous scaffolding throughout in the form of nuclear matrix.
Detailed explanation-2: -A protein found inside the nucleus of a cell. It is involved in making DNA, RNA, and proteins. It also helps control how certain genes are expressed (turned on) in a cell. Nuclear matrix protein 22 may be found in higher than normal amounts in the urine of patients with some types of cancer, including bladder cancer.
Detailed explanation-3: -Nuclear matrix is an intricate meshwork of proteins spread throughout the nucleus. Matrin 3 plays a role in essential nuclear functions, which include gene expression, RNA splicing, RNA export, and nuclear protein import and export.
Detailed explanation-4: -The term “nuclear matrix” (NM)1, 2 implies a structure consisting mainly of nonhistone proteins which remain after extraction of chromatin, casually lipids and residual DNA from isolated cell nuclei. Morphologically the NM consists of extracted nucleoli, nuclear envelope (lamina) and intranuclear fibrogranular network.
