**Background of Recombinant Human DKC1 Protein**
The human DKC1 gene encodes dyskerin, a conserved nucleolar protein critical for ribosome biogenesis and telomerase stabilization. Naturally, dyskerin partners with H/ACA small nucleolar RNAs (snoRNAs) to guide pseudouridylation of ribosomal RNA (rRNA), ensuring proper rRNA processing and ribosome assembly. It also interacts with the telomerase RNA component (TERC), stabilizing the telomerase complex essential for telomere maintenance. Mutations in DKC1 are linked to X-linked dyskeratosis congenita (DC), a rare genetic disorder characterized by bone marrow failure, premature aging, and cancer predisposition, highlighting its role in genome stability and cellular homeostasis.
Recombinant human DKC1 protein is engineered using expression systems like *E. coli* or mammalian cells to study its molecular functions and dysregulation in diseases. This purified protein serves as a vital tool for *in vitro* assays, including rRNA modification studies, telomerase activity assays, and interaction mapping with snoRNAs or telomerase components. Researchers utilize it to model DC pathophysiology, screen therapeutic agents, and explore mechanisms underlying cancer and aging. Its recombinant production also supports structural studies, enabling insights into mutation-induced conformational changes. By bridging basic research and translational applications, recombinant DKC1 protein advances our understanding of ribosomopathies, telomere disorders, and potential targeted therapies.
