PNLDC1 (Piwi-Interacting RNA Pathway Nuclease DC1) is a conserved ribonuclease critical for piRNA biogenesis, a class of small non-coding RNAs essential for germline development, genome integrity, and transposon silencing in animals. In humans, PNLDC1 is predominantly expressed in the testes and ovaries, where it processes long piRNA precursors into mature piRNAs by trimming their 3′ ends, enabling their interaction with PIWI proteins to form functional complexes. Defects in PNLDC1 are linked to male infertility due to impaired spermatogenesis, as observed in animal models and human studies.
Recombinant human PNLDC1 protein is typically produced using heterologous expression systems (e.g., insect or mammalian cells) to retain enzymatic activity. Its structure includes a conserved catalytic domain with endonuclease activity, though detailed structural insights remain limited. Researchers utilize recombinant PNLDC1 to dissect piRNA processing mechanisms, study transposon regulation, and explore links between piRNA dysfunction and diseases like cancer or infertility. Recent studies also suggest roles beyond germ cells, implicating PNLDC1 in somatic tissues and potential oncogenic pathways. However, its regulatory networks and broader physiological functions are still under investigation, making it a focal point in reproductive and RNA biology research.
