La SMC3 gene provides instructions for making a protein that is part of the structural maintenance of chromosomes (SMC) family. Within the nucleus, SMC proteins help regulate the structure and organisation of chromosomes.
Normal function
La SMC3 gene provides instructions for making a protein that is part of the structural maintenance of chromosomes (SMC) family. Within the nucleus, SMC proteins help regulate the structure and organisation of chromosomes.
The protein produced from the SMC3 gene helps control chromosomes during cell division. Before cells divide, they must copy all of their chromosomes. The copied DNA from each chromosome is arranged into two identical structures, called sister chromatids, which are attached to one another during the early stages of cell division. The SMC3 protein is part of a protein group called the cohesin complex that holds the sister chromatids together.
Researchers believe that the SMC3 protein, as a structural component of the cohesin complex, also plays important roles in stabilizing cells' genetic information, repairing damaged DNA, and regulating the activity of certain genes that are essential for normal development.
Although the SMC3 protein is found primarily in the nucleus, some of this protein is transported out of cells. The exported protein, which is usually called bamacan, may be involved in sticking cells together (cell adhesion) and cell growth. Bamacan is a component of basement membranes, which are thin, sheet-like structures that separate and support cells in many tissues. Little else is known about the function of this protein outside the cell, but it appears to be important for normal development.

Tests génétiques
Tests génétiques is a type de medical test that identifies changes in chromosomes, genes or proteins. Genetic tests examine a person's DNA in a variety of ways to assess a person's genetic health. We all have 46 chromosomes in our cells. Chromosomes are made from DNA (deoxyribonucleic acid). Genes are short sections of DNA and each chromosome.

Vieillissement
Ageing (also spelt aging) is the process of becoming older. This happens continually throughout life. It may also be that the presence or absence of certain genes allows people to live longer. With repeated dividing, the telomeres - protective structures at the end of the threads of genes (chromosomes) - become shorter, exposing the chromosomes to.
