Function

TAP19_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).[1]
