[https://www.uniprot.org/uniprot/TAP45_TETTS TAP45_TETTS] Component of a CST-like subcomplex of the holoenzyme telomerase ribonucleoprotein complex, which stimulates telomerase complementary-strand synthesis (PubMed:26551074). Telomerase is an essential ribonucleoprotein enzyme that copies new telomeric repeats onto chromosome ends by repetitively synthesizing the short telomere-repeat sequence 5'-TTGGGG-3' using an RNA template component TER (PubMed:26551074). The CST-like subcomplex (also named 7-4-1) binds telomeric single-stranded DNA and coordinates telomere G-strand and C-strand synthesis (PubMed:26551074).<ref>PMID:26551074</ref>
-
Tetrahymena telomerase holoenzyme subunits p75, p45 and p19 form a subcomplex (7-4-1) peripheral to the catalytic core. We report structures of p45 and p19 and reveal them as the Stn1 and Ten1 subunits of the CST complex, which stimulates telomerase complementary-strand synthesis. 7-4-1 binds telomeric single-stranded DNA, and mutant p19 overexpression causes telomere 3'-overhang elongation. We propose that telomerase-tethered Tetrahymena CST coordinates telomere G-strand and C-strand synthesis.
