WebThe telomerase is coded by the telomerase gene, of which the expression is normally low, can be promoted through the influence of hormones like testosterone. Activation of the gene for telomerase is realized via the associated promoter-gene ( a type of on- and off- switch, see Fig. 12) so that the telomeres can be, at least partly, restored. WebNormal Function. The TERT gene provides instructions for making one component of an enzyme called telomerase. Telomerase maintains structures called telomeres, which are composed of repeated segments of DNA found at the ends of chromosomes. Telomeres protect chromosomes from abnormally sticking together or breaking down (degrading).
