== Function ==
 +
[https://www.uniprot.org/uniprot/LARP7_TETTS LARP7_TETTS] RNA-binding protein required for assembly of the holoenzyme telomerase ribonucleoprotein (RNP) complex (PubMed:15131081, PubMed:15696174, PubMed:16507983, PubMed:17322903, PubMed:20713447, PubMed:22315458, PubMed:22705372). 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:15696174, PubMed:17322903, PubMed:20713447). TAP65/p65 specifically binds telomerase RNA template TER and is required for biogenesis and placement of the TER stem-terminus element: TAP65/p65 first protects the 3'-end of TER from degradation and acts as a chaperone to correctly fold TER for protein binding; it then bends TER stem-loop IV to position it for interaction of stem-loop IV with catalytic TERT RNA-binding domain (PubMed:15696174, PubMed:17322903, PubMed:20713447, PubMed:22315458, PubMed:22705372).<ref>PMID:15131081</ref> <ref>PMID:15696174</ref> <ref>PMID:16507983</ref> <ref>PMID:17322903</ref> <ref>PMID:20713447</ref> <ref>PMID:22315458</ref> <ref>PMID:22705372</ref>
