产品介绍    Telomerase is a ribonucleoprotein enzyme essential for the replication of chromosome termini in most eukaryotes. It elongates telomeres. It is a reverse transcriptase that adds simple sequence repeats to chromosome ends by copying a template sequence within the RNA component of the enzyme. Telomerase are large DNA-protein complexes with telomerase expression being the subject of recent research due to its link to cell immortalization. Recent evidence has shown that MYC upregulates the catalytic subunit of telomerase, TERT, and that Telomerase is a ribonucleoprotein polymerase that maintains telomere ends by addition of the telomere repeat TTAGGG. The enzyme consists of a protein component with reverse transcriptase activity, encoded by this gene, and an RNA component which serves as a template for the telomere repeat. Telomerase expression plays a role in cellular senescence, as it is normally repressed in postnatal somatic cells resulting in progressive shortening of telomeres. Deregulation of telomerase expression in somatic cells may be involved in oncogenesis. Studies in mouse suggest that telomerase also participates in chromosomal repair, since de novo synthesis of telomere repeats may occur at double-stranded breaks. Alternatively spliced variants encoding different isoforms of telomerase reverse transcriptase have been identified; the full-length sequence of some variants has not been determined. Alternative splicing at this locus is thought to be one mechanism of regulation of telomerase activity. [provided by RefSeq, Jul 2008].    

端粒酶逆转录酶hTERT是构成端粒酶的组分之一，是端粒酶活性的必需和限速成分，水平决定细胞端粒酶的活性。抑制hTERT可降低端粒酶的活性，从而抑制瘤细胞生长。目前对hTERT的研究已成为端粒酶研究的热点问题，已发现TERT蛋白表达在肿瘤诊断中有重要意义，并制备了hTERT抗体及应用核酶技术等来抑制hTERT蛋白的表达，抑制端粒酶活性，从而抑制肿瘤的生长。
端粒反转录酶又称端粒酶催化亚单位 （hTRT；Telomerase catalytic subunit；HEST2；Telomerase-associated protein 2；TP2；Telomerase reverse transcriptase；telomerase catalytic subunit）是细胞永生化及恶性肿瘤发生过程中的端粒酶活化的主要限速步骤。hTRT基因表达可以反映端粒酶活性，与端粒酶活性具有平行关系。
