TERT sequences
The telomerase reverse transcriptase (TERT) is the essential protein component of the telomerase ribonucleoprotein. TERT is composed of four structural domains: telomerase essential N-terminal (TEN), telomerase RNA binding domain (TRBD), reverse transcriptase (RT), and C-terminal extension (CTE). TEN contains a telomeric DNA-binding site, for processive repeat addition, and RNA-interaction domain 1 (RID1), important for telomerase RNA (TR) pseudoknot binding. TRBD contains RNA-interaction domain 2 (RID2), which has been shown to bind TR CR4/5 and is important for enzymatic activity. The RT domain contains the catalytic core for nucleotide addition by a two-metal system and both the RT and CTE contain residues which affect processive repeat addition.


Below are details on the TERT sequences: the scientific and common name where applicable; the length and GC content for the cDNA; the length, the isoelectric point (pKI), the molecular weight (MV), the sequence (.seq button) for the amino acid sequences; the genbank accession numbers that are linked to the record at the National Center for Biotechnology Information (NCBI), and original literature citations that are linked to the published online journal. The sequences are organized by general taxonomy. The GC% content, length in amino acids, isoelectric point, or molecular weight are not provided for predicted and putative sequences.
