RNA-binding protein required for assembly of the holoenzyme telomerase ribonucleoprotein (RNP) complex (PubMed:11080168, PubMed:12665556, PubMed:15208446). Specifically binds telomerase RNA and promotes its assembly with catalytic subunit p123, thereby stimulating enzymatic activity and processivity of p123 (PubMed:15208446). Telomerase is a ribonucleoprotein enzyme essential that copies new telomeric repeats onto chromosome ends and functions to maintain cell division (PubMed:11080168, PubMed:12665556). Component of the telomerase holoenzyme complex composed minimally of the catalytic subunit p123 and the telomerase RNA template component. Localizes to the macronucleus. A ribosomal frameshift occurs between the codons for Met-86 and Lys-88. The mature form of the protein is a protein of 43 kDa, which is derived from a 51 kDa precursor by proteolytic cleavage. Belongs to the LARP7 family.
