| + | [https://www.uniprot.org/uniprot/TEB1_TETTS TEB1_TETTS] Single-stranded DNA (ssDNA)-binding protein that mediates the recruitment of telomerase to telomeric DNA (PubMed:19941821, PubMed:20363756, PubMed:25225329, PubMed:22143754). Telomerase is an essential ribonucleoprotein (RNP) 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:19941821). Acts as part of a replication protein A (RPA)-related subcomplex of the holoenzyme telomerase ribonucleoprotein complex: TEB1 specifically recognizes and binds telomeric ssDNA, thereby mediating the recruitment of the holoenzyme telomerase RNP complex to telomeres (PubMed:19941821, PubMed:25225329, PubMed:27895115). TEB1 is related to RPA1 subunit of the RPA complex but is specific to telomeric DNA, which is not the case of RPA1 (PubMed:25225329).<ref>PMID:19941821</ref> <ref>PMID:20363756</ref> <ref>PMID:22143754</ref> <ref>PMID:25225329</ref> <ref>PMID:27895115</ref> | ||
