Polyclonal Rabbit Affinity Purified E B
The 3' ends of chromosomes are capped with telomere sequences (TTAGGG; 6-26 nucleotides in length) by ribonucleoprotein telomerase during DNA replication. Telomerase is an unusual RNA-dependent DNA polymerase that uses an RNA component as a template to lengthen telomeres. The telomeric RNA contains a sequence complementary to TTAGGG. In ciliated protozoa and yeast, telomere length is maintained by regulating the activity of telomerase. Many mammalian cells do not express telomerase resulting in the shortening of telomere with each cell division, and ultimately causing chromosomal instability, aging and cell death. Recently, introduction of telomerase into normal human cells has been shown to extend normal cell life by ~20 doublings. Purification of telomerase from the ciliate also revealed two proteins of 43 and 123kD. p123 is a homolog of yeast Est2 (Essential for Telomerase activity). Mammalian homologs of yeast Est2 (also known as TP2 for Telomerase associated Protein 2; hEST2 or telomerase catalytic subunit or telomerase reverse transcriptase, TERT) have also been cloned (human Est2, 1132aa; mouse Est2, 1122aa; ~127kD).
