Nuclear Assembly Factor 1 (NAF1) is a conserved eukaryotic protein critical for the biogenesis and assembly of telomerase and small nucleolar ribonucleoprotein (snoRNP) complexes. As a homolog of the Shq1 family, it primarily functions as a molecular chaperone, facilitating the maturation of H/ACA snoRNPs by stabilizing key interactions during RNP assembly. In humans, NAF1 is essential for telomerase RNA (TERC) processing and telomerase complex stabilization, directly linking it to telomere maintenance and cellular longevity. It transiently associates with dyskerin (DKC1) within the telomerase RNP, ensuring proper localization and activity of telomerase, particularly in stem cells and cancer cells characterized by high telomerase activity. Dysregulation of NAF1 is implicated in telomere biology disorders, such as dyskeratosis congenita, and cancer progression due to aberrant telomere elongation. Recombinant human NAF1 protein, typically expressed in *E. coli* or mammalian systems with tags (e.g., His, GST), enables *in vitro* studies on telomerase regulation, snoRNP assembly mechanisms, and drug discovery targeting telomere-related pathologies. Its structural domains, including the dyskerin-binding region, are of particular interest for mechanistic and therapeutic exploration.
