Interaction of human telomerase with its primer substrate.

Abstract excerpt

Telomerase is a ribonucleoprotein responsible for maintaining the ends of linear chromosomes in nearly all eukaryotic cells. In humans, expression of the enzyme is limited primarily to the germ line and progenitor cell populations. In the absence of telomerase activity, telomeres shorten with each cell division until a critical length is reached, which can result in the cessation of cell division. The enzyme is...
