Recombinant human DIS3L (rhDIS3L) is a protein of interest in RNA metabolism and disease research. DIS3L, a member of the RNase II family, functions as a 3'-5' exoribonuclease involved in degrading specific RNA substrates, including aberrant transcripts and certain non-coding RNAs. Unlike its homolog DIS3. a core component of the nuclear exosome, DIS3L primarily localizes to the cytoplasm and operates independently of the exosome complex. It plays critical roles in RNA quality control, including the turnover of hyperpolyadenylated RNAs and uridylated substrates.
Dysregulation of DIS3L is linked to human diseases. Biallelic mutations in DIS3L2 (the gene encoding DIS3L) are associated with Perlman syndrome, a congenital overgrowth disorder, while somatic mutations are implicated in cancers such as Wilms' tumor and hematologic malignancies. DIS3L also regulates telomerase RNA component (TERC) degradation, impacting telomere maintenance. Its loss may cause pathogenic RNA accumulation, triggering cellular stress or apoptosis.
Recombinant DIS3L, typically produced in bacterial or mammalian systems, enables functional studies on enzyme kinetics, substrate specificity (e.g., oligo-adenylated or uridylated RNAs), and interactions with RNA-binding partners like LSm complexes. It serves as a tool for probing RNA decay pathways, developing therapeutic strategies targeting DIS3L-related disorders, and exploring its role in cell cycle regulation or transposon RNA control. Structural studies using recombinant protein further reveal how DIS3L's domains, including its catalytic RNB and N-terminal cold-shock domains, coordinate substrate recognition and enzymatic activity.
